Have you ever wondered how many bacteria you swapped with the last person you kissed or how snails eat?

The answer to questions like these can be more shocking than you'd expect.

With some facts, once you've learned their secrets, you'll wish you never did.

recognition centers of the brain, meaning the person becomes unable to associate emotions with

their own body and no longer recognizes themselves as a living being.

Some convince themselves that they have been condemned to eternal damnation on earth,
