Yeah it would be fun and romantic and all that, my point is that you are fooling yourself with the kungfu bit. You will attain crap to mediocre level skills at best, simply because you have zero background and you're too old. But if you're after a unique/strange experience - go for it. Don't worry about the injuries as they wont be that bad because they won't push you hard anyway because they want your money and they are there to give you the experience you are after. Just be prepared for people like me to laugh at your clips once you come back and start promoting yourself as a Wudang teacher.

Sorry to sound so negative. Ran into a lot of people like you (and also like the people that are taking your money) in China over the years.

Personally I think you are better off studying qigong or calligraphy or something similar if you are intent on the China experience.
