Makes you sweat extra?

Anti-antiperspirant cancels out.
I love how it takes 5 people to completely dismiss the entire purpose of the post, strictly because I accidentally wrote 'anti' twice. I made a spelling error on perspirant, which apparently as itself is not a word, and went to fix it before posting.
You wear deodorant to smell nice, you wear antiperspirant to not smell like an ape after you work out at the gym.
Yes, your body uses sweat to cool down. Except it did that a couple thousand years ago because there was a lack of this crazy thing called Air Conditioning. Or better yet, a shower. Hell, even the FAN works. You don't need sweat anymore. If anything, when combined with those three things, it drops your body temperature TOO low.
