If they follow other proposals, they are going to start increasingly intrusive medical exams at age 40. This reminds me of when the USAF started requiring treadmills on all their fighter pilots. They got a massive number of false positives with no actual true positives that wouldn’t have been detected by just the regular ECGs. The reason they knew they were false positives is because they did cardiac catheterizations on all of them. Eventually even the Air Force relented.
Cognitive testing has an even higher rate of false positives than ECGs. Think about having to do a Hogan at every exam. And if you score any different than you did last, you fail.
