The lack of an association between pilot age and crash risk may reflect a strong healthy worker effect' from the rigorous medical ...Monkey's memory cells caught in the act of learning

Also, the signals are hard to detect if the learning task is too difficult or too easy, resulting in only shallow increments of learning.
