My new job is quite demanding, but I don't write much code. My time appears to be too valuable for that now... Now I review reviews of code other people have reviewed that someone else has written. It sounds less invigorating than it really is. Look up "lot campaign" and "recall" and you'll have an idea of the intensity.
I interviewed at a company that traded stocks to make money, and they asked me if I could handle the stress of working on a system that meant a loss of hundreds-of-thousands of dollars if it went down for a day. "Phhhfft. I've blown more money than that in micro-seconds with bad control code.", isn't the right answer. I don't think they were interested in my personal sanity and coping mechanisms.
