HEALTH-- Sunlight-- vitamin D-- confusing

Here's another piece on health related to sunlight. [+] I've seen some confusing reports on this over the past few years-- one of the most bizarre being that sunscreens CAUSE cancer-- not the sun light... and vitamin D taken orally is bad for you-- the only way to deal with this is a good quarterly alphabetically indexed publications. Newspaper and magazines ought to all have alphabetical indecies as well as catalogs.
