Smell
Humans can detect at least one trillion different smells. Tests have found that women have a more developed sense of smell than men, and are capable of identifying a greater number of different odors. Smell is the first sense to develop with unborn babies. Like the five different tastes scientist believe that there are seven different smells- musky, putrid, pungent, camphoraceous, ethereal, floral and minty. Good smells make us happy if we find it pleasant it can have a positive effect on the mind and help to lift our mood.
