cont.   There are about 1 million individuals playing football each year.  There are 103.1 million individuals riding bicycles.  Thats a ratio of about 100 to one.  You state that twice as many individuals suffer head injuries riding bicycles as playing football.  OK, if I accept that, the probability of incurring a brain injury playing football is FIFTY TIMES AS GREAT as incurring the same injury riding a bicycle. 

You speak of "informed" decisions...great, I agree.  However, it's important that those decisions not be based on misleading information.  Gary Crum
