Amen. When I lived in Africa I didn't have electricity or running water. As soon as it got dark I was finishing up dinner and headed to bed. I stayed up a little to read but that just used up my batteries or candles so I didn't do it that much. You really get used to moving with the sun and coming back to America was a shocker for my body. I think my quality of sleep is better here purely because I eat more fat (if I don't get enough my sleep suffers) but I really miss movin with the sun.
