The Times reported some startling statistics from the NFL concussion settlement. Described as conservative by the NFL team, numbers like these are still pretty scary:
"The N.F.L.’s actuaries assumed that 28 percent of all players would be found to have one of the compensable diseases and that the league would pay out $900 million to them. Their calculations showed that players younger than 50 had an 0.8 percent chance of developing Alzheimer’s or dementia, compared with less than 0.1 percent for the general population. For players ages 50 to 54, the rate was 1.4 percent, compared with less than 0.1 percent for the general population. The gap between the players and the general population grows wider with increasing age."
