OP, I guess this is true with any cardio based activity you can do for an hour a day or so. It's certainly my "secret wepon" to try and be around (and fully functional) for my son's high school graduation and possible college years. I'm 49 and my son is 4 so you do the math...

LOL, am guessing that @genec is being a bit cheeky. We could always let ourselves go and be fat couch potatoes.

Setting: @genec and I are sitting on a couch and watching a movie. We have a big bowl of chips and some soda.
Me: (BURRP!) Hey Gene! Pass the CHIPS!



Edit: "In addition, those who cycled part of the way to work still saw benefits – this is important as many people live too far from work to cycle the entire distance." This is why I do the Park n' Ride (car and bike).
