Heard this on KGO-AM earlier this week - this is a 3 minute audio link:
Researchers have known for a few years that there's a connection between lack of sleep and obesity. Now there's a biological explanation.
Also, the October issue of O Magazine features an article titled "The Five Things you Must Do to Age Beautifully" and getting enough sleep is one of those five things (a condensed version of the article is available on the Oprah website here)
So...if you wanna keep the weight off and age gracefully - get your Z's!
