Ask Slashdot: What To Do With New Free Time?

An anonymous reader writes "After 25 years of doing IT (started as a PC technician and stayed on technical of IT work through out my career) I've been moved to a position of doing only on call work (but paid as if it is a normal 9-5 job). This leaves me with a lot of free time... As someone who's used to working 12+ hours a day + the odd night/weekend on call, I'm scared I'll lose my mind with all the new free time I'll have. Any suggestions (beyond develop hobbies, spend time with family) on how to deal with all the new free time?"
