Sex With Neanderthals Boosted Our Immunity

Scientists make 'stunning' discovery in genome comparison

(Newser) - Three years ago, scientists thought humans had never had sex with Neanderthals.

Exercise Curbs Colds, Even Cancer

Moderate, regular activity is like a 'drug' that boosts immune system
