A whole bunch of studies have found that Helmets don't actually prevent concussions, and neither do mouth guards. In fact that helmets are only really good for injuries such as a broken skull. One study was done here in Winnipeg also found that concussions last a lot longer then first thought, sometimes up too a year, this could have huge ramifications on skiing and other sports where head injuries are regular.
So NS I am curious, if these preliminary studies prove to be accurate will you feel more comfortable without a helmet/do you feel a helmet is necessary as it is at all?
