I never read the book, but during the last couple years I became more attentive to things in life. Nothing special, but just the general flow of life so to speak. I started noticing an interesting pattern. There is pretty much always exists a single solution to any problem. A core solution. A polymorphism in programming could be an example of what I mean. Say you have a program with a bunch of similar entities and a ton of if/else statements handling the logic for various cases. Conditions keep growing with each new entity. The code becomes messy as you fight the language trying to "cure" your program. Then you introduce an interface and suddenly everything becomes more clear and things just _make sense_. Your conditionals slowly disappear, the logic gets simpler and the code is now flat.

I keep noticing similar patterns pretty much everywhere in life and somewhat confident that the same core solution exists for aging as well.
