„Existují pouze tři sporty: býčí zápasy, motorismus a horolezectví; zbytek jsou pouhé hry.“

There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely games.

Based on a 1957 Ken Purdy quote, first mentioned in a posthumously published interview with Alfonso de Portago: note: :“I have a quotation in a story, a piece of fiction that won't be published until this summer,” I told Portago, “something that I thought at the time I wrote it you might have said: that of all sports, only bull fighting and mountain-climbing and motor-racing really tried a man, that all the rest are mere recreations. Would you have said that?”
I tend to agree with Hemingway who said something to the effect that only mountain climbing, bull fighting and automobile racing were sports and that everything else was a game.
