Just watched a pretty interesting doco called 'Eat The Sun'. It was released last year. Its about 'sun gazing'... looking directly into the sun for up to 40 odd minutes a day.
Apparently you start off at 10 seconds on the first day and then every day after that increase your sun gazing by 5-10 secs. The best time of the day is the 1 hour period after sunrise and the 1 hour period before sunset.
A lot of people who do it find their energy explodes, their stress vanish and funny enough so does a lot of their appetite. Some of these people claim to not have eaten food for YEARS.
Its an interesting doco.
Me?... well I LOVE my food too much to stop eating food but would be interesting to give it a try for 5-10mins a day.
