hey, good job. I'm between 60 and 65.
what kills me is people who think that going on a 10 mile hike, or biking to work is some gargantuan, strenuous, fitness-freak outing. "you bike from Bellevue... wow". actually, no, that's not much of a physical exertion - get off the couch and try to do something...
i did get off my couch once, fell and hit my face on the foot stool...decided nope, not doing that again..."hey son, would you mind fetching the remote...that's a good boy!"
