I´m involved with the internal martial arts, currently I´m doing Chow Gar. I have heard that because of the training methods in the south Chinese systemsn (White Crane, Bak Mei, Southern Mantis) there is a health risk inherent in the training. I´ve heard its possible to die from energy despersion when one is middle aged, if you get a little sick and has to stay in bed for some time. Then you can´t maintain the tension you have build up, and in a few weeks, there is a chance you start getting cancers or organs going wrong. Anyone with knowledge on the subject that wants to elaborate on it?
