I never wore a helmet as a kid (maybe that explains a lot), because they didn't exist. Now that I'm older, if I ride, I wear a helmet, and I always had my kids do the same.
Getting back to my earlier point, which fact best explains the over 50% reduction in head injuries?
1. Kids riding bikes less often
2. Construction of millions of dollars of bike trails
3. Parents mandating that their kids wear helmets
4. Better helmet designs
5. City run biker safety training program
The biker safety program may or may not have done some good, but if you don't adjust the data for the number of bikers, and the time they spend riding, you will never know. The same will apply to football. If they design better headgear, and implement rules against "targetting", they may make the game safer, but if at the same time, you see a 30% increase in the number of plays, you may never know if they other things actually accomplished some good.
