My friend Myenna just told me that her health teacher, my gym teacher hasn't used deoderent in 30 yrs! How gross is that? He sais deoderent isn't good for you. Personally, I'll use deoderent ,because it stops me from sweating and it smells good. I should say to him haven't you always said that personal hygiene is important? I think using deoderent is a part of personal hygiene. I just can't get over how gross that is!
