Speaking of workouts, I do a bit of walking throughout the city, too. It's such a densely populated place that driving short errands is more trouble than anything, so we shop for groceries on foot. Some people use carts, but like many others, my wife and I just buy as much as we can carry in a trip which is rarely more than a half mile. I like my bags to be heavy, and I walk really hard. Also when I take the subway, I might have a heavy bag or two, and I walk up the stairs really hard, two at a time. It uses a burst of energy which doesn't last long but I suspect does some good. We moved back to the city four years ago, and since then I've lost a lot of weight. When I see someone who hasn't seen me in a while, they seem a little shocked to see me. I'm down to my college weight and size. One downside is that just about all of my clothes are much too big on me now.
