Double the milk? Does that mean we can have double the cookies too? The American Academy of Pediatrics is recommending double doses of Vitamin D for kids, because it may help prevent serious diseases - cancer, diabetes and heart problems - down the road. That means children would need to down four cups of milk daily, or take Vitamin D supplements.

The recommendation is still controversial - some scientists say there isn’t enough evidence yet of the Vitamin D-cancer link. Get the scoop here.

A European study found that listening to iPods and other personal music players at high volume may impact - surprise! - your hearing. People who rock out at high volume for five hours a week are funneling more noise into their eardrums

And kids may not realize the damage until years down the road, when they’re 30 years old and saying, “Ehhh?
