This is on going debate. Currently both side throw in studies, PHDs, here and there. One side said it causes cancer, stop using it. One side said you get exactly the same effect by standing under the sun, why don't you just never go out. And at the end, at least for now, there is no convincing winning argument.
Heck, I got 3 uncles, plus a sister-in-law that are doctors and they split exactly at middle, 2 and 2. |
