I'm into my sixth decade, and I will agree with you that it's about detail. I find more and more rabbit holes to go down that are just fascinating. I make ice cream, but how can I make really good ice cream? What are the pros and cons of regular switches vs. leaf switches for the retro arcade controller I want to build? Why does putting a bunch of wood mulch around my fruit trees do so much to improve the soil ecology? The list goes on. I am never bored.

I think many people take the availability of information we have at our fingertips today for granted. It wasn't always this way. Dig into it, learn something, rinse and repeat.
