Lol stop it dude. I am 47 and just joined. 33 is far from too old to being any journey... Just take it easy on the older guys like me once you get the hang of things. Good luck !

I started BJJ at the age of 49, six years ago.
It's a much harder road being older, but the system is great and you just need to listen to what your body says.
The best day to start 10th Planet is today no matter where you are at.
I started 10th Planet (Downtown Las Vegas) at 47, BJJ at 45...now 49. While the "warranty" on the body does run out at 40, It just means we have to be more honest with our expectations and recovery.
I've found the 10th Planet folks to be phenomenal and even as a large guy (6', 250 lbs), I've yet to run into a technique that is impossible.
