Well, yes, people do, and the trick is to love your work and your company. I was definitely doing so when I was doing my own startup. I've worked before in a place that was mostly people who just show up for a 9 to 5 (or often more like a 10 to 4). It just felt super-depressing to me to look up around at 6pm and the whole floor is completely empty. Didn't last long there, but I guess it was a nice sabbatical. These days I work closer to 10-12, but if I'm on a good pace in a groove, or someone needs help with an urgent issue, or it's just some self-imposed mental deadline, that can easily stretch the day to past midnight. I would say most of my peers work similarly.
