Lifespan is not appealing, unless you have a quality of life worth living. One maxim I've enjoyed is "Live each moment as if, if you were going to live it internally, that, that would be a good thing". Then, things (longevity) get really interesting. This is what is meant to be gleaned from Peter Attia's term "healthspan". It suits what it is. It just sounds dorky.
good (lifespan) = X
First off, if how you derive meaning in life is by doing good in the world, --whatever that looks like for you-- then poor lifespan is a non-starter. In other words, good is a function of lifespan.
One definition of better that I like, a nihilistic proof definition, is "everything you used to be able to do, and more". It's perfectionistic in nature. It's still an interesting one. Lifespan is the most obvious example of how can actually implement this.
Good is also a function of performance, of sorts, but they have to be factored into the equation of your life in a fascinating way
Thinking about why I have an obsession with the bulletproof lifestyle I have a few thoughts. Specifically there is this cluster of ideas that is very enticing. This being:
There is an effortless way to what you want, if you make the right decisions for your aim, strategically. Or in summery. Better choices.
The term "upgraded" summarizes it nicely, as well as the BP diet book's chapter 2's title “What you think is good for you might be making you fat, sick, and stupid“
This is what is captivating about Bulletproof.
Underplaying the role of hard work, unlike every fitness anything, is probably this "philosophy's" biggest downfall, while being its largest conversion asset.
Anyhoo, these are just some thoughts on lifespan, healthspan, bulletproof, and the like. I'm still working on clarifying my thoughts on how longevity should optimally be thought about for us humans. I'd be a delight to hear how other people think about this if you wouldn't mind leaving a comment.
See ya leter,
