8. No, I don't believe hockey is nearly as bad as football

All the hitting in hockey is when you're more or less upright, you lead with the shoulders and hips. Granted, there's the occasion when your helmeted head smacks the glass or you go down and you smack the ice but that's not all the time. (I played up through college).

In football there are certain players whose helmet/head is involved in nearly every play. That, I believe, is the problem.

Also, there's an article in Popular Science about advances in helmet technology which help prevent concussion. One of the things they admit is that helmet manufacturers are reluctant to upgrade their products for fear that would be seen as an admission that there is something wrong with their current products. One of the interesting items in that article is that it's been found that rotational forces are a bigger contributor to concussions than linear forces. Unfortunately nearly all current helmet technology is designed and tested for linear forces.
