Mainly because of Testosterone. If men start taking progesterone, (as in female re-assignment programs), then the hair stops forming on the legs and arms.
testosreronone yes, but the real reason is to block the pores from infection or parasites in vital areas...armpits, chest, head etc
All mammals have hair, even mammals that "appear" bald (e.g. whales, pigs, etc.). Among primates, humans have the least amount of body hair/fur. Evolutionarily speaking, it is not entirely clear why men tend to have more body hair (and facial hair) than do women. However, there are probably a couple of things going on:
1. Sexual selection. At various times in human history, hairier men may have been chosen as sexual partners/mates more than smoother men because for whatever reason this was more appealing to women. This probably explains at least facial hair, which is not unlike manes seen in other mammals such as lions, etc. Body hair correlates in part to testosterone, so sexual selection may have preferred body hair for this reason as well.
2. Protection. Men with hairy chests, shoulders, or backs have natural protection against mosquitoes and insects, and human populations in insect-prone areas do tend to be hairier. This protection also means protection from diseases spread by insects. Body hair can also regulate body temperature a bit, keeping someone warmer or cooler depending on the context.
3. Genes/hormones. Male body hair varies dramatically from one man to the next: this is determined in part simply by genetics and hormones in an individual.
There is one kind of "out-there" hypothesis called the Aquatic Ape hypothesis that holds that humans lost most of their mammalian hair during a phase when prehumans were living in a semiaquatic environment, perhaps along lakeshores or seashores. By this theory, women ended up with less hair because they spent more time in the water, whereas may spent more time on shore. Again, this is not a mainstream hypothesis, but it's one idea of many.
One reason why men may have hair on their chests is because it increases their reproductive capacity.
It is interesting to note that the corresponding region on the female body, the mammary gland and nipples are highly erogenous zones whereas in males the nipple seems to be much less sensitive. I postulate that the reason men have hairy chests is that, merely by being in close contact with a woman, through hugging, especially at night, that the chest hair may stimulate arousal in the woman without any active participation of the male, who may very well be asleep with his partner lying on his chest. A woman who is aroused more easily by a particular male is more likely to produce his (in this case hairy chested) offspring.
men are able to grow beards due to a hormone released at the base of the man's penis. this hormone stimulates hair follicles in the facial area and enables a beard to grow.
men get so hairy because hair sokes up sweat and keeps you from getting infections easaly

The leaves are slightly hairy.
the answer is the plant has very hairy smooth leaves.
Temperate climate. You have many organism variation; some very hairy, some hirsute. Climate gets very cold. Those very hairy organism can survive long enough to reproduce and give their progeny their hairy traits. Thus the hairy mate with the hairy and the variation is more on the hairy side, so hair is selected for in this cold and immediate environment.
The Northern hairy-nosed wombat is significantly larger that the Southern hairy-nosed wombat.
God created men to be hairy
This is untrue. Most gay men are not hairy.
medium hairy
no.
hairy testicles
yes
Some do, some don't. Everyone's taste is different.
yes they are I agree, I made a little survey and found that hairy guys made love to there wives a bit more often than men that were not so hairy, of course this is only a rough estimate, some men who are not all that hairy are of course sexy too, if nothing else, to some women, hairy men seem more sexy than than hairless men.
There is only one option: embrace your hairiness. Many men who are hairy find that they are more comfortable being hairy the older they get; many men don't mind being hairy once they meet a partner who is into hairy men (there are lots of people out there who like hairy men); many men feel more self-confident if they work out and develop pronounced muscles, which makes being hairy feel more comfortable. Find a solution along these lines, because in all honesty you have better things to do than shave large portions of your body every day.
