What to write?

It's been two weeks now and I'm still in bed immobilized. The pain is not getting better and it won't in weeks. The skin under my cast is itching like crazy half the time. I usually can't concentrate enough to have a conversation or even watch tv anymore.

So what can I do to stay occupied? I can't research or write anything too terribly substantive but maybe I can rant about something I already know about? What could I spout opinion on, preferably something I'm pissed off about since I'm in pain already?

Any ideas? Give me something to think about.
