Why vultures don't get sick when they eat dead animals
It's important to note that many animals eat carrion, vultures are fairly unique in that they're able to eat carrion that has succumbed to the effects of decay and disease, a feat few stomachs in the animal kingdom can match.

The Truth About The Surprisingly Recent Invention Of The Tea Bag
Legend says that brewing tea dates back to around 2737 BC, when tea leaves fell into water being boiled for Emperor Shennong of China.
