Some of the absolute worst pilots I've flown with were those with "more life experiences" but having recently started flying. In fact, I can think of only one exception to this statement.
The fact is that reaction and adaptability go down over time- better have good in field experience to make up for that, which this CA certainly had.
The scariest FO's I flew with at the regionals were mid-late life career changers. They were nice and trying hard, but meaning well doesn't mean you know well...
The FO was my friend's roommate- RIP to all involved.
