Krank does have a wee point actually, take advantage of the injury to get out and do other things. Getting your mind off climbing slightly can help avoid boredom when you're back at it again. So technically skydiving, or whatever, is all part of your mental training for climbing again...
If you're anything like me, you can gain just as much from CV training (weight loss) as strength training, but i doubt that's the case if you're campussing. A bit of running can still be a good idea though...
Or you could just spend some time with your other half for once, or find one for that matter....
