Any fool could see that Marc Márquez coming back to race at the second race in Jerez, after breaking his arm in the first race, was a bad idea. The fact that he has had to have a second operation to replace the plate in his arm merely confirms this.
But MotoGP racers are no ordinary fools, of course. Like all elite athletes, they are driven to extraordinary lengths to compete, taking extraordinary risks, pushing their bodies and minds to the limits of their abilities, and all too often, beyond. They do not consider whether something might be a bad idea or not.
For a MotoGP rider, the short term is the next practice session, the medium term is the race on Sunday, the long term is the championship standing at the end of the season. Anything beyond that is not relevant to the job at hand, which is to try to win races and titles.
That blinkered focus means that they are, as a rule, incapable of taking sensible decisions about their health, in either the short or the long term. But it is precisely that same blinkered focus which has brought them to where they are, racing at the very highest levels of the world championship. The ability to exclude anything that doesn't directly involve racing from their minds and devote all of their mental and physical energy to racing is what makes them so successful.
The decisions of MotoGP racers are foolish in the long term, but when viewed from the warped perspective of an elite athlete, they have an internal logic and consistency which makes sense to them. As I said, MotoGP racers are no ordinary fools...
