Why would men want hair transplants? Why would women want botox? There is something magical about youth. I think. Or maybe it is to please the men, who find it attractive. Women wouldn't want to do it, if the men find it undesirable or repulsive. All the 'comfort' reasons are secondary. I would think that this whole poll is most relevant from a man's perspective, as women are just as much pawns in this sexual game as the men who build up cave-manly muscles to impress women.
