"Why are some people seen as attractive and others not? And why have we evolved to find some features attractive and others not? According to new research, it may all be down to oxidative stress and antioxidants. Psychologists have discovered that men who were rated as the most physically attractive by women have the lowest levels of markers of oxidative stress. 'These findings have several important implications,' says psychologist Dr Steven Gangestad who led the study. 'They fit in with the idea that women evolved to find particular features attractive because those features are related to low levels of oxidative stress.'"
