Tanning is one of those rare activities that when done in moderation is still bad for you. Recent research proves that even sunscreen doesn't protect you from harmful UV and UVB rays that can cause skin cancer. But like with cigarettes and unprotected sex with strangers, some human beings seem bent on destroying themselves.

With that in mind, we put together a gallery that is both a cautionary glimpse of the damaging effects of the sun as well as an ode to the stupefying and painfully irrational Homo sapien behavior.

Enjoy, and for God's sake, don't let this be you.
