I have the luxery of having a DVD player in my bedroom as well as in my livingroom, because I'm chronically ill.
When I get so bad that I'm put on bed rest by my doc, I watch a whole lot of DVDs, and I love to read.
I never get bored really, my computer is in the room next to my bedroom, so it's not far away.
I play a lot of online games, I do jigsaw puzzles (I know, makes me sound like a 60 year old) I keep myself entertained.
I really don't mind bedrest, as long as it's not too often.
I buy magazines and save them up for those times.
It requires a little planning ahead.
