The phrase "get a life" could make me feel that way, as well. As I age, though, I see the shortness of life more clearly. There is the distinct possibility that someone who enjoys programming 80 hours/week will in the future realize he/she devoted all of his/her time to work and never took a spin through the other aspects of life.

My bet, though, is that often enough people who are absorbed in their work also enjoy other things. I've seen plenty of posts on HN regarding going for a walk to think and clear his/her mind.
