Replying to Productive injured activities

So my season in Japan has been cut short by 3 broken metacarpals in my right hand. Back in the UK and am wondering what I'm going to with myself.

Whilst I'm sure NS and left handed masturbation will take up a decent amount of time, I will probably get bored eventually.

I'm already going to work on my Spanish, and try and read a lot, but yeah any other ideas would be great.
