The best naps are those who last 15 minutes, that way your body does not have the time to fall in full-sleep mode, so you actually wake up feeling rested. Worked great when I was working the night shift.
That would be like being with a woman for 15 seconds, pulling out and calling it good. I don't think so, I don't like to be teased. If I don't get at least 6 hours 4 days a week I'm a grouch.
