When I was younger I would tell stories of all the bones I have broken, how fast I have been in cars and motorcycles, how deep I've been, etc... Now that I am a little older, I am paying for the physical punishment I have put myself through every morning I wake up or when it rains. I am still paying for the 145mph speeding tickets and arrests I had. And I am REALLY lucky nothing happened to me by deep diving without proper training.
Now, I brag about my son (of course) and my job. I love helping others and love it when others help others. Kinda wish the "pay-it-forward" idea was more widespread.
Other than those two things, I don't feel the need to compare what I have done to others which is what really is going on when someone brags. I love diving and the experiences I have from that are simply stories told for entertainment. Stories around the boat, or at the resort, or around the fire, or whatever, are fun times spent with friends. Good times, good times.
