This is the strangest thing. Achillie locks and other ankle locks hurt like heck and tapping often seems like a pain-tolerance thing. Well, lately I noticed that by laughing, the pain seems to go down enough that I can concentrate and counter the sub. Does laughing help increase one's pain tolerance during submission attempts? P.S. I know that I shouldn't make mistakes and let them get those holds in the first place... I'm still learning and figuring out how to do that!
