You should also work while standing up.

There's a reason why academics prefer whiteboards and chalkboards to pen and paper. It's because they feel genuinely more productive and creative while working on them. I personally think that it comes down to improved blood flow, and it's one of the key tricks that my friends and I used to earn physics degrees from Caltech. We'd go camp out in empty lecture halls late at night, filling chalkboard after chalkboard with scrawl, and only sit down to copy finished problems in their final form.

I like standing up while reading and doing more free-form work like exploring ideas. But for concentrating on specific problems or focused study, I need to be sitting down. I just can't concentrate my efforts as well when standing.
