Knowing how to give up

I've left this one last because it's a bit controversial. We always hear that giving up is not an option. But there are situations where it doesn't make sense to insist if it's going to harm you. In jiu-jitsu, when the blow is landed and could hurt you, what's the option? The three slaps, it's part of the game. That way you maintain your integrity so you can fight again. You give up in the moment so that you can continue training, learning and fighting.
