> So it behooves me to eat a quick lunch and return to work.

As you stated, it's not for everyone. I went from a position with a mandatory half hour lunch to one where I had an optional lunch up to an hour long. I find that I'm much more productive when I take a full hour for lunch, and then stay an extra half hour after when I would normally leave. It really breaks up my day, and time doesn't seem to drag on towards the end of the day.

It also helps that I live close to work, so I can go home and play with my dog for a while. She has really good ideas, and has helped me get through some conundrums.
