No, it’s not the bean sprouts and tofu. It’s not even the great year-round climate that encourages people to do stuff outdoors. It’s the hills. The Bacon family has hiked and biked a lot of hills over the past three days and we’ve eaten a lot of food, but the hills won. I swear I have cinched in my belt buckle by a notch.

As I recall, one of the largest concentrations of superannuated (really old) people is in the Caucasus Mountains. The Georgians, Armenians and Azerbaijanis get lots of exercise walking up and down mountains. Living around hills is healthy! I don’t recall seeing a single fat person in San Francisco. (OK, maybe a couple of hefty people but no obese people). I’ve seen more little old Chinese ladies on walkers chugging up the hills in Chinatown than I’ve seen fat people.

Oh, maybe I should add that it’s not just the hills. It’s the hills in combination with the sidewalks. San Francisco is a walking town. The city has great streetscapes and no matter where you are there is an abundance of destinations within walking distance. People walk places, and when they walk, they walk on hills. It’s that simple.
