inb4midichloriansWhat they did was double the amount of mitochondria in the mice or rats or whatever. This had the effect of making them live twice as long, be able to last twice as long, eat twice as much, and be five times angrier. It also made them unusually skinny, though, probably as a result of their incredible metabolisms (mitochondria-> powerplants of your cell)
So what this crap does is make angry sex freaking awesome?!be able to last twice as long, eat twice as much, and be five times angrier.
