I have no idea why you're being downvoted. I'm the same way. I don't take lunch breaks unless I'm completely wiped out mentally. I get to go home earlier, but also I get to keep focusing on what I enjoy doing. Also, the office is empty and quiet, which is pretty damn nice. People here seem to be making the assumption that we're grinding ourselves to the bone by not taking a break - but, no, if I need a break, I can take one. I just don't need to.
