Question

why do we are having hairs on are body

Answer 1

$<marquee>☺☺Hi there☺☺</marquee>$

There are eccrine glands, which are found on most of the body and open directly to the surface of the skin (needed for cooling), and apocrine glands, exclusive to the hairiest bits, which empty body odor-carrying fluid into the hair follicles. Thicker, denser hair helps hold on to that scent and then disperse it.
