'When you're the flame, you can't get burned!!'
Sounds freaky, but I know of a group in London who swear by the power of intention, and it states that if you intend to stay healthy then you will.
Illness can only penetrate a damaged energy field, and a healthy person can not be taken ill. Lots of athletes get frequent bugs by over training and eating poorly, as this weakens your immune system/ energy field.
I know from experience that there is some truth in this, however I can not claim to be the jedi master at it yet. That's why I keep quoting the 'way of the warrior' motto until it sinks in.
