A saying of the US Marines

The more pain a Marine endures, the stronger he becomes.

If a Marine feels pain after working out, it means he had a good workout and physical weakness is leaving his body.
protester: "ouch my lungs hurt from smoking pot, and my arms hurt from holding this protest sign."

Marine: "Pain is weakness leaving the body."
