Why Don't Animals Get Sick From Rotten Meat?

Vultures eat rotting carcasses crawling with anthrax and walk away healthier. Hyenas barely get sick despite constant exposure to rabies and disease. Crocodiles heal wounds in bacteria-filled swamp water with almost no infection. And for decades, scientists were completely wrong about how Komodo dragons pull off the same trick. This video breaks down four completely different survival strategies predators evolved to eat what would kill a human in hours, and why humans took a totally different evolutionary path to solve the same problem.
