There you go comparing other sports again.

THE TOPIC IS NOT ABOUT NASCAR. IT'S NOT ABOUT FOOTBALL, SOCCER, BASKETBALL OR ANY OTHER SPORT.

Giving up? A triangle choke chokes off the oxygen supply to the brain, you have no choice but to tap, it's not giving up. If that is giving up, then a boxer who is not physically capable of getting up off the mat is giving up. I guess they could go until they no longer have the capability to stay conscious, but the body usually disagrees and forces the tap.

And boxers give up too. Duran gave up in one of boxing's highest profile bouts ever. So I guess boxing isn't a sport.
