The Invisible Man–The Daily Mail reports on a new study that says men begin to lose their sex appeal to younger women at the age of 39. Characteristics that contribute to the ‘invisible man’ are grey hair and a double chin. 52% of the study pool explained that men lose their edge as they approach 40. Another factor was that 62% of the women surveyed think that men in this age pool are taken. Famous male celebrities in this demographic that are comparable at the age of 39 include Hugh Dancy, David Beckham and Bradley Cooper.
