Knitting for your Health

Here's a clip from the Early Show, a segment about knitting and crocheting being good for your health. But we already knew that, didn't we? I really loved it when the neuroscientist from the Mayo clinic said "these types of intellectual activities, might be, somewhat, neuro protective". Needleworkers show less memory loss; it helps to manage stress, pain and depression; helps to strengthen the immune system, and decreases blood pressure.
I don't know about the rest of you, but I think I'll crochet instead of jog.
