All i know is that i feel miserable if i dont get sunlight for extended periods (months) and i feel fantastic (again) after 20-30 minutes of shirt-less sun exposure. It's not the heat, it lasts for days.

The cold doesnt bother me, i sunbath in the winter too. This obviously isnt for everyone.

Even if it is bad for me i dont need anyones help. Let them go shut down Burger King and Jack Daniels and whatever enjoyable bad things people do.

That said, thanks for the science.
