I went running today, in the rain. I don't go running too often, since I don't like it much, but I'm temporarily between gyms, and was feeling unusually virtuous. Anyway, I'm going along the lake-shore path and suddenly I see, oncoming, a guy with no legs. Running. Fast. I mean, the guy did not even have any knees. He had an impressive pair of prosthetics with curious, long, flexible feet. His gate was slightly odd but he didn't seem in the slightest danger of falling. And as I said, he was very fast. (Faster than me.) I mean, and it was even raining and everything. He also looked really happy. It was one of more inspiring sights I have ever seen.
So here's the thing. You can say that technology has its dark side. You can even say that medical technology may have its dark side. But this guy's legs? That's the bright side, and the existence of things like that, which give a guy that kind of freedom--I guess I just think it's worth a lot.
