Are you actually headed to the Shaolin village in China? If yes then let me tell you right now, FORGET ABOUT IT!
I was 21 once and coincidently had similar thoughts. Lucky for me the Shaolin village mountains are around 140 klmtrs. We were highly impressed with our few visits by the dicipline and the girls and scenery and the struggle and what not. Enrolled for 6 months, lasted 9 days.
You might be mentally and physically stronger than me back then but still its not for us.
If its anything other than the legit shaolin school, go for it.
