I think with an extra 40 hours free time a week for a year I could catch up with everything I want to see in a year. That's 2000 extra episodes of 1hr TV I could watch. I reckon I could manage it while also watching a couple new shows.

Games are a bit different, usually I play one or 2 time intensive games in a year but I don't expect to play all the big releases even with no job. 3 or 4 years should allow me to catch up with the ones I feel like I've missed and want to play in the last 5 or 10 years though.
