Our sweat kills germs, even TB

I was surprised by this story.

Sweat spreads highly efficient antibiotics on to our skin, which protect us from dangerous bugs. If our skin becomes injured by a small cut, a scratch, or the sting of a mosquito, antibiotic agents secreted in sweat glands, such as dermcidin, rapidly and efficiently kill invaders. These natural substances, known as antimicrobial peptides (AMPs), are more effective in the long term than traditional antibiotics, because germs are not capable of quickly developing resistance against them.

If you're not a Republican, you learn something new every day. Our sweat can even kill TB. So go outside and work up a sweat right now. It's a good thing.
