vitamin d - why you need sunlight

Sunlight’s good for your skin and critical to your overall health and well-being.
Get enough of it, and you’ll actually reduce your risk for a wide range of cancers. What sunscreens are very good at is blocking UVA rays. Yet even that presents a problem, because your skin needs exposure to UVA rays to make vitamin D.
That’s a huge problem, because vitamin D is a vitally important nutrient that insures healthy function in just about every system in your body.

Vitamin D’s also the most potent cancer fighter in the world. A report came out of a Nebraska university showing that vitamin D has the potential to lower the risk of all cancers in women over 50 by 77 percent. 1 And in a study published in the journal Anticancer Research last October researchers found that sunlight – about 20 minutes a day for fair-skinned people, and two to four times that much for those with dark skin – can reduce the risk of death from 16 types of cancer, in both men and women. Sunscreens rob you of all these health benefits.

democrats and republicans

A woman in a hot air balloon realized she was lost. She lowered her altitude and spotted a man in a boat below. She shouted to him, "Excuse me, can you help me? I promised a friend I would meet him an hour ago, but I don't know where I am."

The man consulted his portable GPS and replied, "You're in a hot air balloon, approximately 30 feet above ground elevation of 2,346 feet above sea level. You are at 31 degrees, 14.97 minutes north latitude and 100 degrees, 49.09 minutes west longitude.

"She rolled her eyes and said, "You must be an Obama Democrat."

"I am,"replied the man. "How did you know?"

"Well," answered the balloonist, "everything you told me is technically correct. But I have no idea what to do with your information, and I'm still lost. Frankly, you've not been much help to me."

The man smiled and responded, "You must be a Republican."

"I am," replied the balloonist. "How did you know?"

"Well," said the man, "you don't know where you are or where you are going. You've risen to where you are due to a large quantity of hot air. You made a promise you have no idea how to keep, and you expect me to solve your problem. You're in exactly the same position you were in before we met, but somehow, now it's my fault."
