As people age they focus, or tend to, on the things they are losing, the things and faculties that are worsening, the situations and events that are sliding into chaos or decay. It is all part of the default pessimism of most cultures. Why is this the default setting? Because a culture is living YOU if that makes sense. You’re like a single cell and your existence serves the culture, to some extent, but since the culture is not alive- it has been created by humans- it is parasitic on human energy to keep it alive. Like the matrix it feeds off our vital forces, and that drain is experienced by us as pessimism. Without its supply of human energy the vampiric culture dies, it displays itself as energy hungry and casts aside those who cannot blindly feed it- therefore it prefers the young to those who have wised up, the old.
Yep, that’s the first benefit of aging, you’ve seen through the culture. You know you have to pay lip service and do your civic duty but that’s it. No overtime here will gain you anything. Your energies are better spent relating to real people.
As you get older is makes sense to focus on that which CAN evolve and improve:
You get to be less self-centred (if you try)
You become better at detecting subtleties
You see the bigger picture
You can predict things better
You have more foresight
Now the harder part- which requires work:
You can be less anxious
You can be more lighthearted
You can give more in every sense
Faced between making a heavier response and a lighter one you can choose the lighter one
You can learn more effectively
You can better identify worthwhile goals
You can be more use to people
The list could be longer but this is a start. The real regeneration of any culture begins when old age is seen as a revered and worthwhile goal not some kind of horrible garbage bin end to a beautiful, prolonged and self-centred childhood.
