People today distinguish between knowledge and action and pursue them separately, believing that one must know before he can act... . They say [they will wait] till they truly know before putting their knowledge into practice. Consequently to the end of their lives, they will never act and also will never know.

If you really want to find out something about immortality, you have to live in the mountain forests for 30 years.
