Hi,
I partially agree with Markfromcali, but at his age I don't think he can reach that state consciously, martial arts like most tings shoud be seen as a step in life not the the end.
The are very good for the body and can make a loner many friends and a bit of respect by his peers. Which can help reach and test what Markfromcali was saying.
I've done martial arts during the development years and I've been out of it for 10 years, my body is still able to do things that most people can never do and I have so many good memories. what more can you ask from it....
It' a bit like basketball when you're young you think your only option is to jump all the way to the basket when you grow older you learn that you can be much better and run a lot less if you're able to throw the ball from the 3 pionts line.(Michel Jordan)
