With regard to the concept of training oneself …
A man in jail who fought with the guards was put in solitary confinement. Part of the punishment in solitary confinement included sleeping on the hard floor and being forced to take ice-cold showers.
When he was released from solitary confinement and returned to the regular prison, he gave away his mattress and slept on plywood and he continued to shower with cold water.
He thus deprived them of the ability to punish him by these methods because he became used to it.
He did this because he knew he would continue to fight the guards.
