We can always re-examine our priors and assumptions given the current context. It's also worth considering other fields. For example, military helicopter pilots training is longer, more expensive, and frequently only requires a 6-8 year commitment. It doesn't pass a sanity check that a 25 year career should be too much of a concern... if they were treated well.
