Hell for a man that's 46 years old (as of 10/30) you can't tell. I'm in very good shape, better shape than 95% of the guys younger than me. I went to train and rolled (sparring) with a bunch of guys bigger, more advanced and younger than me. They told my Teacher which he then said to me "you made impression up at the main school. They though you were in your 20/30's. They couldn't believe how tough and strong you were"

I'm not a rippling stud but I have my abs, I'm lean and I give everyone a tough time no matter what rank.
