What armpit hair

The scientists have several hypotheses about what function is performed by the hair growing in the armpits. First and foremost, in the armpits are lymph nodes. Exposure to UV light can lead to very unpleasant consequences – cancer. Dense vegetation also protects the area from sunlight. Hair reduce the friction that occurs while walking, while moving arms are held along the body. Another version is that the hair perfectly absorb odors, including the natural secret to having a musky scent attracting the opposite sex. The thicker the hair, the brighter the smell and, therefore, more attractive people. At least, so certainly believed by the ancient people until then, until he decided that the shaved armpit look more aesthetic.
The smell of sweat remains on the hair. In the air it oxidizes rapidly and becomes unpleasant, so the ability to absorb odors doesn't always work for the benefit of man.
