I was reading your post below, and remembered a poem I wrote in High School.
Very Intellectual!!!
You take a little hair and you take a little sweat,
Put them together and what do ya get?
I say arm pits, arm pits!
Now the hair starts to wiggle, and the sweat starts to flow,
And before you know it, ya got BO!
I say arm pits, arm pits!
HAHAHAHA
Use a good antibacterial soap first of all, and then an anti-perspirant. The brand MITCHUM is pretty good.
Just read the labels at the store.
