i have a theory that old people do less because they have a good supply of dopamine. brain concludes everything is fine so it does nothing. the mind is at rest.

It is actually a good thing that the new generations have lost for most part. You know, just dive deep in your thoughts and let your mind wander. The constant never ending inflow of information doesn't really allow for a time to think and plan.
Not saying everyone who is just staring ahead is really thinking deep thoughts, but it allows for sorting things out... kinda like defragmenting. Remember defragmenting hdds? No? No?! Oh no, I'm so old... 🧟🧟♂️🧟♀️
