I was talking to a friend yesterday who told me she has never worn a deoderant/antiperspirant as she doesn't need one. She believes that if you don't start using them you will never need one. I tend to disagree with this as I know that when I get hot I do perspire and body odour is caused when the sweat becomes stale. Are you the kind of person that doesn't perspire much and could get away with not using one? It would certainly save money.
