> You have kids don't you? That seems to be a consistent feature of people I meet who espouse the virtues of going to work.

Yes. But my liking of bike commuting is maybe more related to the fact that it is a positive change from using public transportation, where I felt really miserable (had to take two crowded buses with an indeterminate waiting time in-between).

But you are right that having kids changes one's view to work... often, after an intense weekend, I go back to the lab and say "finally! I can relax and get some work done".
