I think more like they want and try to be better than others.
They push to limit even they know they cant.
Some they dont know their limit.
Even they know they alredy overlimit, when asked can continue ka bro? They answer yes sure can, no problem. Then during game they started to tongkat use racket alredy. Lulz!
I believe this involved ego also. If fast tired and weak their feel maruah tercalar.
Me during young only play competitive game. Now more to just exercise and get sweat alot. Not into too much aggressive game that require more strength and stamina.
