I think the real world championships occur every minute of the day where helicopter pilots rescue persons off mountains, longline logs, service offshore oil rigs, show humanity their planet, transfer patients from roads to hospitals, fight fires, muster cattle, keep cell towers working, service oil and gas reserves and ....
Yes, possibly. But does that mean we shouldn't have the world championships? Because if so, then logically...
We'd better stop all car racing/rallying, because the real championships take place with all the long distance truck drivers, taxi drivers, and anyone else who drives for a living.
And we'd better get rid of horse racing and show jumping, becasue the cowboys do it better.
As for mountain walking, the "Three Peaks" and similar challenges, well, the mountain rescue teams would win hands down if they bothered to enter.
Forget all martial arts championships; the police, bouncers, bodyguards etc are doing it every day of the week.
As for writing competions; hey, I write for a living; what do these people think they're doing - bloody amateurs having short story writing competitions!
Etc, etc etc etc etc.
