Also @TheYinDragon: I think that psi and life force are different (unless you are using chi/Qi/Ki) Since psi is mental energy, I think that the worst that you can get are headaches, and feelings of dejection. I have also experienced physical exhaustion during overstraining, so I don't really think that you can change your life force through this.

Just an opinion. :D
