John Ralston says we know enough to start doing something.  We do not need to wait until we know everything before we begin implementing protective measures they may lead to CTE.  We did not have to wait until we had all the data from the highway departments to know that seat belts save lives, nor do we need to wait to begin preventing brain trauma. Thank you Grant Beaman for serving our country and protecting our freedom.
