There seem to be differences in males and females. I suspect much of it is due to nurture. I know one area in which my wife and I differ is our appreciation of all things fragrant. I like flowers, I like those nice smelling air fresheners etc, but to be honest I would never think of actually buying any. Yet my wife considers them essential. I don't have a problem with this - I don't mind in the least, but I have to admit that I would not even notice if our stocks of all things fragrant ran down.
What is hilarious at the moment are the attempts by cosmetics companies towoo blokes into caring and buying creams and stuff. "Men! Does your (tough) skim turn to leather when you shower?(In a manly way). (My brackets). This is for some post showering lotion stuff. They are attempting to fuel men's egos by doing this laughable balancing act between tough and looking after yourself.
They use a tough voice, leather images, model/ actor/ references to manly things etc etc. All for the cash in your pocket. Hre's the US version.
