Women recognize unmarried men by smell.

Australian scientists conducted an experiment in which they asked 82 heterosexual women aged 18 to 35 to rate male body odors. The researchers found that the body odor of a single man seemed more pleasant to most women. In addition, the more attractive the men's fragrance was, the higher the participants in the experiment rated their appearance. Perhaps the difference in smell is due to the fact that married men have better health and hygiene than single men, as well as testosterone levels and dietary habits.
