Mountain Bike: Another way to fir your body

Mountain biking is an exciting sport that can be enjoyed by anyone who knows how to ride a bike. Compared to the average bike ride, it does present some danger. Therefore, you should master these basic skills before you hit the trails or the
dirt.

You can practice these beginning skills at a local park, school, bike path, or simply around your house. If you can, try to find a location with a steep hill.

Get a feel for your pedals Practice moving your foot away from the pedal, first while sitting on your bike with one foot on the ground. Next, move on to releasing and replacing your foot while pedaling around for a bit. Those with toe clip and clipless type foot pedals will want to spend a bit more time
practicing.
Sit and spin for position Simply sit on your bike and pedal around. You should keep your arms slightly bent. You should also adjust your seat height so your leg is 70 to 90 percent extended at the bottom of every stroke on the pedal. Keep your body relaxed, as there will never be a position where you should have
either your knees or your elbows locked.

Shifting gears
Get a feel for shifting gears with your bike. The higher gears are harder to pedal and will go faster while the lower gears are easier to pedal and will help you ascend hills. As you get to steeper hills, its best to shift before you get
to the hill rather than while your on it.

Coasting
You should spend a bit of time coasting while standing on your pedals, without actually sitting on the seat. Keep your arms bent but don't lock your knees. Now, try experimenting with shifting your body towards the rear end of the bike.

Pedal while standing
You should get as comfortable as you can with pedaling while standing on your bike. Try lifting yourself off the seat while standing on the pedals,
then crank them around. You should try this in higher gears on flat ground then again in lower gears while on a hill.

Dropping down a curb
Try finding a curb where you can easily get to the upper portion of it. Practice at a moderate speed,standing and coasting right off the curb from the
upper level to the lower level. Try this at different speeds until it becomes second nature.

Once you practice these techniques and get the hang of them, you'll be able to hit the trails feeling comfortable on your mountain bike. Even though it may take some getting used to, it'll become second nature before you know it.

Alchohol Effect On Our Blood

Dr. Richardson, in his lectures on alcohol, given both in England and America, speaking of the action of this substance on the blood after passing from the stomach, says:

"Suppose, then, a certain measure of alcohol be taken into the stomach, it will be absorbed there, but, previous to absorption, it will have to undergo a proper degree of dilution with water, for there is this peculiarity respecting alcohol when it is separated by an animal membrane from a watery fluid like the blood, that it will not pass through the membrane until it has become charged, to a given point of dilution, with water.

It is itself, in fact, so greedy for water, it will pick it up from watery textures, and deprive them of it until, by its saturation, its power of reception is exhausted , after which it will diffuse into the current of circulating fluid."

It is this power of absorbing water from every texture with which alcoholic spirits comes in contact, that creates the burning thirst of those who freely indulge in its use. Its effect, when it reaches the circulation, is thus described by Dr. Richardson:...

"As it passes through the circulation of the lungs it is exposed to the air, and some little of it, raised into vapor by the natural heat, is thrown off in expiration. If the quantity of it be large, this loss may be considerable, and the odor of the spirit may be detected in the expired breath.

If the quantity be small, the loss will be comparatively little, as the spirit will be held in solution by the water in the blood. After it has passed through the lungs, and has been driven by the left heart over the arterial circuit, it passes into what is called the minute circulation, or the structural circulation of the organism. The arteries here extend into very small vessels, which are called arterioles, and from these infinitely small vessels spring the equally minute radicals or roots of the veins, which are ultimately to become the great rivers bearing the blood back to the heart.

In its passage through this minute circulation the alcohol finds its way to every organ. To this brain, to these muscles, to these secreting or excreting organs, nay, even into this bony structure itself, it moves with the blood. In some of these parts which are not excreting, it remains for a time diffused, and in those parts where there is a large percentage of water, it remains longer than in other parts.

From some organs which have an open tube for conveying fluids away, as the liver and kidneys, it is thrown out or eliminated, and in this way a portion of it is ultimately removed from the body. The rest passing round and round with the circulation, is probably decomposed and carried off in new forms of matter.

"When we know the course which the alcohol takes in its passage through the body, from the period of its absorption to that of its elimination, we are the better able to judge what physical changes it induces in the different organs and structures with which it comes in contact. It first reaches the blood; but, as a rule, the quantity of it that enters is insufficient to produce any material effect on that fluid. If, however, the dose taken be poisonous or semi-poisonous, then even the blood, rich as it is in water and it contains seven hundred and ninety parts in a thousand is affected.

The alcohol is diffused through this water, and there it comes in contact with the other constituent parts, with the fibrine, that plastic substance which, when blood is drawn, clots and coagulates, and which is present in the proportion of from two to three parts in a thousand; with the albumen which exists in the proportion of seventy parts; with the salts which yield about ten parts; with the fatty matters; and lastly, with those minute, round bodies which float in myriads in the blood (which were discovered by the Dutch philosopher, Leuwenhock, as one of the first results of microscopical observation, about the middle of the seventeenth century), and which are called the blood globules or corpuscles.

These last-named bodies are, in fact, cells; their discs, when natural, have a smooth outline, they are depressed in the centre, and they are red in color; the color of the blood being derived from them. We have discovered that there exist other corpuscles or cells in the blood in much smaller quantity, which are called white cells, and these different cells float in the blood-stream within the vessels.

The red take the centre of the stream; the white lie externally near the sides of the vessels, moving less quickly. Our business is mainly with the red corpuscles. They perform the most important functions in the economy; they absorb, in great part, the oxygen which we inhale in breathing, and carry it to the extreme tissues of the body; they absorb, in great part, the carbonic acid gas which is produced in the combustion of the body in the extreme tissues, and bring that gas back to the lungs to be exchanged for oxygen there; in short, they are the vital instruments of the circulation.

"With all these parts of the blood, with the water, fibrine, albumen, salts, fatty matter and corpuscles, the alcohol comes in contact when it enters the blood, and, if it be in sufficient quantity, it produces disturbing action. I have watched this disturbance very carefully on the blood corpuscles; for, in some animals we can see these floating along during life, and we can also observe them from men who are under the effects of alcohol, by removing a speck of blood, and examining it with the microscope. The action of the alcohol, when it is observable, is varied.

It may cause the corpuscles to run too closely together, and to adhere in rolls; it may modify their outline, making the clear-defined, smooth, outer edge irregular or crenate, or even starlike; it may change the round corpuscle into the oval form, or, in very extreme cases, it may produce what I may call a truncated form of corpuscles, in which the change is so great that if we did not trace it through all its stages, we should be puzzled to know whether the object looked at were indeed a blood-cell.

All these changes are due to the action of the spirit upon the water contained in the corpuscles; upon the capacity of the spirit to extract water from them. During every stage of modification of corpuscles thus described, their function to absorb and fix gases is impaired, and when the aggregation of the cells, in masses, is great, other difficulties arise, for the cells, united together, pass less easily than they should through the minute vessels of the lungs and of the general circulation, and impede the current, by which local injury is produced.

"A further action upon the blood, instituted by alcohol in excess, is upon the fibrine or the plastic colloidal matter. On this the spirit may act in two different ways, according to the degree in which it affects the water that holds the fibrine in solution. It may fix the water with the fibrine, and thus destroy the power of coagulation; or it may extract the water so determinately as to produce coagulation."

Bad Bread Threatment

Bad breath is a common health problem in the society.Offenssive smell from the mouth may be due to various reasons.The main reason is the presence of anaerobic bacteria in the biofilm formed on the tongue.These bacteria degrades the proteins present in the food resulting in the production of some offenssive gases like hydrogen sulphide,skatol ect.

Bad odor from the mouth in the early morning is seen in almost all individuals.This can be controlled by maintaining oral hygiene.Even after cleaning the mouth some individuals may suffer from bad breath due to some problem in the mouth or in the nearby areas.Some general disease condition can also produce bad breath.Exact cause has to be identified and should be treated accordingly.Some common measures to cure or reduce bad breath are discussed here...

1) Oral hygiene:
Mouth should be kept clean every time to reduce the bacterial action.After food gargling with lukewarm water is very essential.Even after small food articles like snacks,sweets,buscuits cleaning with water is needed.Brushing should be done twice daily.It is said that early morning brushing is for beauty and bed time brushing is for good health.

2) Brushing techniques:
Normal brushing technique should be followed for better result.Many people brush vigorously causing damage to the gums.Brushing after every food and drink can damage the enamel .Bristles of the tooth brush should be smooth but hard enough to remove the food particles from the gaps.The direction of brushing is the most important thing.The upper teeth should be brushed in a downward direction and the lower in upward direction.This is applicable to both inner and outer surfaces.Next comes the crown of the teeth;here brushing is done in anterior and posterior direction keeping the brush in same direction.This applicable to both upper and lower set of teeth.

3) Tongue cleaning:
White or yellowish coating on the tongue can cause bad breath.This is more well marked in the morning and should be removed twice daily with the healp of a tongue cleaner. Tongue cleaner must be used gently without damaging the taste buds on the tongue.

4) Tooth pick:
Tooth pick is a small strip of wood or plastic with a pointed end.This is used to remove food particles lodged between the gaps.Very useful after eating meat and fish.Should be used gently to avoid damage to gums.

5) Gargling:
After every meal gargling with lukewarm water is useful.For better result little common salt is dissolved in the lukewarm water .Different types of mouth wash is available in the market in different trade names.Gargling with mouth wash can also reduce bad breath.

6) Food habits:
Protein containing food articles are known to produce bad breath. Example; meat, milk, fish, egg etc. If these food articles are taken proper cleaning is essential.Some food articles are known to produce particular smell which may be unpleasent for others. Raw onion is the best example.It is said that an apple a day keeps the doctor away and a raw onion a day keep every body away.Small food articles taken in between can also cause bad smell(nuts,fried items etc).Maintaining regularity in food timing is the most important thing.

7) Water intake:
Dryness in the mouth can make a favourable condition for the bacterial activity resulting in bad odor.saliva is needed to keep the mouth moist and to reduce the bacterial proliferation.Production of saliva is closely related with water balance of the body and hence sufficient quantity of water should be taken to maintain the production of saliva.

8) Mouth freshners:
Natural and artificial mouth freshners can reduce the intensity of bad breath to some extent.Spicy articles are commonly used for this purpose.Chewing spices like clove,cumin seed,cardomom,cinnamon,ginger ect are useful. All citrus fruits can reduce bad odor.Mouth freshners and chewing gums are available in the market.these products are also helpful ,but some may cause damage hence should be used with caution.

If the above things doesn't work then what to do? The Alternative can be consider the following:

1) Remove the cause:
Bad breath is common in some general and systemic diseases like diabetes,fevers,gastric disorders,liver diseases and ect.By removing or reducing the primary cause the bad breath will go automatically.

2) Modern medicine:
If bad breath is due to any infection suitable antibiotics,anti fungal or anti viral medicines will help.If it is due to any autoimmune or chronic inflamatory conditions steroids may also be used.Saliva producing tablets can also be used.

3) Dental cleaning:
Dental cleaning done by a dentist can remove the dental plaques and tartar. This can reduce the severity of bad breath.Visit your dentist atleast once in a year.

4) Filling of caries:
Since caries are one of the main cause for bad breath it should be filled by a dentist.Earlier silver amalgam was used ,nowadays it is replaced by synthetic materials.If the pulp cavity is affected by the caries root canal treatment can be done.

5) Tooth extraction:
If caries are deep with destruction of teeth with bad smell extraction is the better choice and a dental implant can be kept in the gap.

6) Tonsillectomy:
Patients with recurrent tonsillitis can have bad breath due to offenssive discharges and release of pasty materials from the crypts of tonsils.Such patients get great relief after tonsillectomy(removal of tonsils).

7) Psychological counselling:
Those who suffer from bad breath may be very much depressed and they be away from the public .This isolation hampers their daytoday activities.Such people should understand the fact that all humanbeings are having bad breath, but with slight differences in intensities.Mostly all people control it by taking personal care.Every human body has got it's own smell,that may or may not be tolerable for others.They should be adviced to do all hygienic meashures to reduce the intensity of smell.Improving the quality of life by all possible means can also help.Moral support from friends and family members are needed for such people.

Some individuals visit the doctor for bad breath without any real problem.It is included under somatisation disorder.They usually complain about pain, breathlessness,abdominal discomfort,bad smell ect.proper diagnosis is needed to rule out any real causes.These patients should be managed with a psychological approach.

8) Homoeopathy:
In Homoeopathy medicines are selected on the basis of physical ,mental,emotional,and social aspects of the diseased person.Considering the whole aspects a constitutional homoeopathic medicine is selected and given in suitable potency and dose.By this all health related problems including bad breath will be solved.On the basis of coating on the tongue,type of smell,cause for bad breath,and other associated complaints a medicine can be given to get relief from bad breath.In the homoeopathic medical repertory by Dr Robin Murphy there are 140 homoeopathic drugs mentioned for bad breath.On the basis of signs and symptoms of the individual a suitable medicine is given.Commonly used drugs are arnica, antim crud, pulsatilla, sulphur, psorinum, nux vomica, ars alb, merc sol, kreosot, hekla lava, silicea, asafoitida, graphites, kali bich, acid nitric etc.

Homoeopathic mother tinctures like cinnamon Q,kreosot Q,zingiber Q,rhus glabra Q,menthol Q and ect can be used for gargling after diluting in water.

Alcohol and Body Fit

If alcohol does not contain tissue-building material, nor give heat to the body, it cannot possibly add to its strength. "Every kind of power an animal can generate," says Dr. G. Budd, F.R.S., "the mechanical power of the muscles, the chemical (or digestive) power of the stomach, the intellectual power of the brain accumulates through the nutrition of the organ on which it depends.

Dr. F.R. Lees, of Edinburgh, after discussing the question, and educing evidence, remarks: "From the very nature of things, it will now be seen how impossible it is that alcohol can be strengthening food of either kind. Since it cannot become a part of the body, it cannot consequently contribute to its cohesive, organic strength, or fixed power; and, since it comes out of the body just as it went in, it cannot, by its decomposition, generate heat force."

Sir Benjamin Brodie says: "Stimulants do not create nervous power; they merely enable you, as it were, to use up that which is left, and then they leave you more in need of rest than before."



Baron Liebig, so far back as 1843, in his "Animal Chemistry," pointed out the fallacy of alcohol generating power. He says: "The circulation will appear accelerated at the expense of the force available for voluntary motion, but without the production of a greater amount of mechanical force.

In his later "Letters," he again says: "Wine is quite superfluous to man, it is constantly followed by the expenditure of power" whereas, the real function of food is to give power. He adds: "These drinks promote the change of matter in the body, and are, consequently, attended by an inward loss of power, which ceases to be productive, because it is not employed in overcoming outward difficulties i.e., in working." In other words, this great chemist asserts that alcohol abstracts the power of the system from doing useful work in the field or workshop, in order to cleanse the house from the defilement of alcohol itself.

The late Dr. W. Brinton, Physician to St. Thomas', in his great work on Dietetics, says: "Careful observation leaves little doubt that a moderate dose of beer or wine would, in most cases, at once diminish the maximum weight which a healthy person could lift. Mental acuteness, accuracy of perception and delicacy of the senses are all so far opposed by alcohol, as that the maximum efforts of each are incompatible with the ingestion of any moderate quantity of fermented liquid. A single glass will often suffice to take the edge off both mind and body, and to reduce their capacity to something below their perfection of work."
Dr. F.R. Lees, F.S.A., writing on the subject of alcohol as a food, makes the following quotation from an essay on "Stimulating Drinks," published by Dr. H.R. Madden, as long ago as 1847: "Alcohol is not the natural stimulus to any of our organs, and hence, functions performed in consequence of its application, tend to debilitate the organ acted upon.

Alcohol is incapable of being assimilated or converted into any organic proximate principle, and hence, cannot be considered nutritious.

The strength experienced after the use of alcohol is not new strength added to the system, but is manifested by calling into exercise the nervous energy pre-existing.

The ultimate exhausting effects of alcohol, owing to its stimulant properties, produce an unnatural susceptibility to morbid action in all the organs, and this, with the plethora superinduced, becomes a fertile source of disease.

A person who habitually exerts himself to such an extent as to require the daily use of stimulants to ward off exhaustion, may be compared to a machine working under high pressure. He will become much more obnoxious to the causes of disease, and will certainly break down sooner than he would have done under more favorable circumstances.

The more frequently alcohol is had recourse to for the purpose of overcoming feelings of debility, the more it will be required, and by constant repetition a period is at length reached when it cannot be foregone, unless reaction is simultaneously brought about by a temporary total change of the habits of life.

Alchohol And Production of heat

The first usual test for a force-producing food," says Dr. Hunt, "and that to which other foods of that class respond, is the production of heat in the combination of oxygen therewith.

This heat means vital force, and is, in no small degree, a measure of the comparative value of the so-called respiratory foods. If we examine the fats, the starches and the sugars, we can trace and estimate the processes by which they evolve heat and are changed into vital force, and can weigh the capacities of different foods.

We find that the consumption of carbon by union with oxygen is the law, that heat is the product, and that the legitimate result is force, while the result of the union of the hydrogen of the foods with oxygen is water. If alcohol comes at all under this class of foods, we rightly expect to find some of the evidences which attach to the hydrocarbons."

What, then, is the result of experiments in this direction? They have been conducted through long periods and with the greatest care, by men of the highest attainments in chemistry and physiology, and the result is given in these few words, by Dr. H.R. Wood, Jr., in his Materia Medica. "No one has been able to detect in the blood any of the ordinary results of its oxidation." That is, no one has been able to find that alcohol has undergone combustion, like fat, or starch, or sugar, and so given heat to the body.

Reduction of temperature
instead of increasing it; and it has even been used in fevers as an anti-pyretic. So uniform has been the testimony of physicians in Europe and America as to the cooling effects of alcohol, that Dr. Wood says, in his Materia Medica, "that it does not seem worth while to occupy space with a discussion of the subject." Liebermeister, one of the most learned contributors to Zeimssen's Cyclopaedia of the Practice of Medicine, 1875, says: "I long since convinced myself, by direct experiments, that alcohol, even in comparatively large doses, does not elevate the temperature of the body in either well or sick people." So well had this become known to Arctic voyagers, that, even before physiologists had demonstrated the fact that alcohol reduced, instead of increasing, the temperature of the body, they had learned that spirits lessened their power to withstand extreme cold. "In the Northern regions," says Edward Smith, "it was proved that the entire exclusion of spirits was necessary, in order to retain heat under these unfavorable conditions."
