In a stunning, "DUH"-type story, researchers who studied active and non-active twins found that those who work out look better and appear younger than folks who don't.

Shut up! Seriously?

Last time I was a the gym, I was on the cycle next to a woman who clearly worked out more than me.

This is going to come as a surprise, but she looked really young and healthy, despite being in her 40s (I asked her.).

No kidding. I was amazed by it, too.

So guys, here's the story on the study they needed to prove this one. Any thoughts?
