I started when I was 28, Now 38 and just starting to work seroiusly on my flexability. The next oldest person in my class is like 26and I roll with all of them all the time. Get in there, take it slow at first, let everything "tuffin' up". Just relax and just show up to class for the first 3 months or so and let everything develop. After about three months you should be able to really start to push yourself!!!
