Consider the following two videos, both from this season.
Mountain biker Loic Bruni would have every right to hold his head and roll around on the floor after that crash – he’s probably travelling at about 70kph there.
Instead he just gets up, dusts himself off, and gets on with business. He finished fourth in his race the following day.
Compared to Christiano Ronaldo with his agonising “head” injury (the defender doesn’t even touch his head!) that makes him: 1) a better sportsman and 2) less of a whinging little bitch.
