There is no other data set for the 65 and older crowd in a controlled environment than fractionals and charter.
You can look at an apples-to-apples comparison, and see if there's an uptick in incidents and ASAPs as pilots get older.
Smelling your own farts and saying 121 won't have issues because "we're better" is not an honest look at the issue.
