I think programming and exercising is healthier than, say, moving.
As to legal risks - it's not the programmer who's facing them, it's his employer (which is the same thing for the self-employed programmers, but they're few). A programmer will not be personally sued for any sort of "IP infringement".

I didn't consider this angle, because I've always been my own boss. I've never written programs for anyone else, which means I took home the money, not the grief.
But as time passes, I see more and more cases where someone tries to patent something that should never be patented, which might eventually prevent people from writing programs at all.
