I've never understood why you should do the same things in your free time as you do at work. I personally don't and know a ton of programmers and non-programmers who don't as well. Find other hobbys, they are worthwhile too!
I'd advise them to broaden their horizons. Take music lessons or a creative writing class or a welding class or drawing lessons. If there was a subject you wish you had more time for in college, maybe dig back into that.
Or maybe broaden your horizons a little more literally: take some time off and travel.
