Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete.

Not only are there at least a half-dozen glaring problems en route to the conclusion, but the entire study works from an internally flawed premise.
Though you only need a few minutes’ exposure, here’s yet another compelling reason to get a little sunshine daily if you are able to take advantage of it. Vitamin D appears to help prevent both breast and colon cancer, and doctors say the best source is natural sunlight. Experts disagree about ideal exposure times. Fair-skinned recommendations range from 3 minutes to 15 minutes, while darker-skinned individuals may be fine with up to an hour of sunlight daily. Don’t fry to a crisp, though – and a tanning bed is not the same thing.
