A fellow that I toured with twice has the ability to sleep for 5 to 10 minutes and wake up refreshed and can go all day and all night like this seemingly forever with just these periodic short naps. He remains a disgustingly healthy person as well.
To this day I still receive e-mails with photos at all hours of the night as he wanders around taking photographs. All this after working hard all day as a high end cabinet and furniture maker and riding his bike hard after work and/or hiking in the local mountains during daylight.
Unfortunately, I still need my straight eight hours each night. I guess that I was born in the wrong gene pool. It was a challenge touring with him.
