Please no. Winters will be absolutely miserable for one. For another, my internal clock is most comfortable with waking up at 9AM. It doesn't understand numbers and clocks, so in the summer that means 10AM. Going to work at 10 is ok, but 11 starts getting a bit uncomfortable, though luckily I've so far picked jobs that let me do that. But the discrepancy between the clock showing nearly noon and my internal clock believing it's morning does cause me a bit of anxiety. You can always do whatever you want after dark, but I can't sleep when I'm driving to work.
