Why Mona Lisa smiles is a short literature composed by Dianne Lange tells readers why women tend to give more smile than men; the feminine always smile automatically in any situations. However, the difference of smiling seems to be minimal while in a certain context. In addition, when all genders have to work in the medical field, the difference between male and female is reduced substantially as well. I agree more or less with this information because it mundane for women to smile in almost situations, and it is naturally for men to act seriously with fewer smiles, probably of thinking to solve the problems. Nowadays, the society, is also irrefutable that one male who smiles all the time is always presupposed to a gay.
