I looked at a youtube video of a boy that is meditating in the jungle and has not eaten or drank anything for the last 10 months and he looks to be in good health. Also one man that is 78 years old claims that he has not eaten or drank anything in the last 66 years.
I think that the video of the boy is titled Boy with devine power if you want to take a look.
The guy that has not eaten in 66 years says that he gets his energy from the sun. When it comes down to it I guess we all get our energy from the sun indirectly.
So it looks like I am going to have to limit my time in the sun to make sure that I don't get too many of those junk calories from the sun. Maybe I will have to start riding at night.
