You might want to note that many of the answers in response don't ever really reach the level of any measure of a response of "shared experience" type answer. I think many of the responders in the thread...reflect the same answers so many others who spent all that time "learning technique" would give. Therefore they really don't know how to answer a guy who spent that time period learning real martial power.
I am not advocating what the guy learned was real or not, I don't know the guy. I just found his experiences interesting and relevant to the discussion here.
