So what? Are people really not participating in a sport because there is no hope of breaking a WR? Sports are about fun and competition and sometimes exercise.

I’d also argue there is a difference between rules about equipment and rules about technique. Technique rules may have to be adjusted more often because if an athletes does something unusual that is within the current rule set but may be seen as advantageous, you have to make a decision.

With equipment you can just say no. Those Nike running shoes are banned, full body swim suits are banned. The javelin is just another ban. With equipment, it also effects athletes uniformly, everyone must change to the new equipment. So no one is unfairly penalised.

Why do the records need to fall?
