Same old, same old...more old

I've taken my head out of the sand
And signed my Medicare card
Though growing old is indeed what I planned
My soul still feels young—but it's scarred.

Evolution takes too long to, well, evolve. William Goldman said "Nobody knows nothing," and it seems that's true, even after eons of life lessons that should teach us—especially the young—something, but doesn't. Circumstances and the world change, but human nature and people's ways seem to stay the same over time. We watch ourselves and others in dismay over repetitive behavior. What's up with that? 

Nobody listens to nobody else or learns from others' experiences. We each seem determined to have to learn every damn thing for ourselves. Generation after generation. And I'm certainly no different. Probably even worse than many. Sigh. 

I really would like a do-over so I can do better. Does Medicare cover 80% of do-overs?
