For me, it is not "lost interest", I always disliked
- Sports where the results depend on judging (ice skating, gymnastics, equestrian dressage, and all the new X games stuff)
- Why are there four different styles of swimming?
- Why are there so many different distances in track running?
On the other hand, I like sports where you need some versatility (biathlon, triathlon, hepta/decathlon, olympic pentathlon - although the last loses some appeal with the removal of the equestrian part). I could even come up with a few new combination sports:
- King/queen of the runners: each athlete does a 60 m sprint, 400 m hurdles, 3000 m steeplechase (or cross-country), and a marathon.
- King/queen of the ice track: you have to combine runs in luge, skeleton, and bobsleigh.
- Sailor king/queen: First, you let them sail their high-tech, heavily computerized catamarans. In the second round, the skippers have to compete in a $5,000 Optimist dinghy.
