Re: Humans go into heat after all, strip club study finds (Oct. 28): I think there must be a shining and glow in the face (! any increase in the weight) and the beauty in appearance of a human female in the heat or ovulation days.

In the case of animals, will there be any special smell emanated from the body of a female that attracts the male animals from a far distance?
