Curious about trying to start/train in MMA at 32..

Title says most of it, but I am curious if 32 is too old to start training in MMA.

I know it’s a tough sport, but I want to learn a skill that will not only be fun, but also train me to be more disciplined.

My brother is 39 and does Muay Thai, and I don’t do much other than play games.

I want to learn a good sport. Any thoughts?
