I don't know what you mean by accumulated practice, please elaborate? I think for me it came out when I got enough achievements, so yeah I guess I got more time to deal with "secondary issues". I wouldn't call it a secondary thing though, let alone lowering expectations/slowing down. I wasn't talking about pensioner years here lol. Anyway maybe for you it's secondary in importance, I'm not as detached as you I guess. And yes it's learning for the brain, whether deliberate or not.
