My main instructor is in his 40's and is a 5th dan black belt, which is considered a "master" in our federation. He's also a black belt of some rank in TKD and in BJJ. He is a great example of "hitting it too hard" for me: damage to his knees and hips in the past prevent him from doing much above waist level nowadays. Over-extension beat him up pretty bad.
