Boxers, Muay Thai, MMA, etc. and fighters who trains and spars up to full power, are very conscious of injuring their hands. Personally, I injured my wrists the most during the first couple of years. Next were the thumbs. Hands were almost always wrapped. Sometimes forgetting to bring them though. This trained me to be conscious of how much risks I should take hitting pads, bags, etc. when I forgot the wraps. With MMA gloves, it gets riskier with and without wraps. MMA fighters trains both with MMA gloves and Boxing gloves and bare hands. This trains the mind to be conscious about breaking the hands, wrist, etc. Fighting in the streets, I'm way more conscious in picking my shots and my precision + power, are leaps and bounds beyond what it was before I was trained. I don't even bother wearing hand wraps any more (for the last 3 years), while going up to full power on 200-300 lb bags for 10-20 rounds straight....rarely hurting my wrists.
