Maybe you are right. When I was 20 or so, I also used the computer a lot, not so much for programming yet, but for this and this. So I did use the mouse much more than I do now. However from time to time I felt issues with my hands.
So I even bought this heavy Logitech Natural Keyboard, I think things improved a lot. Anyway, from time to time I still had minor issues.
Being 28 now, working since some years fulltime as developer with normal keyboards, I hardly have such issues anymore. Although I have to admit that I pay attention that I get up from time to time. But I am definitely no ergonomics ideal. Half of the time I sit like depicted on the picture on the OP's link and in the evenings even worse when I hack at home on my laptop.
