The Golden Spot of Exercise

2.5 to 4.5 hours per week varied kinds of exercise is the golden spot where people should be aiming for. Does walking count? Yeah, sure, absolutely. Go for a walk in the park. That's it. But also, you know, just viewing my grandmother's lifestyles. My grandmother from my mom's side lived to be 92 and she was pretty healthy most of the time. She was a little overweight, but you know, okay. And then my grandma from my dad's side, she is... I think she's 92 or 93 now. Both of them lived really, really simple lifestyles.
