If you haven’t reached 37 years old yet and you want to know what it feels like, I will describe it.
Essentially I am a 21 year old who has reached a certain level of comprehension for so many things in the world. This includes, but is not limited to: Hardware. Software. Banking and finance (particularly home loans). Human anatomy. The stock market. Cooking, baking. Nutrition. Neurology. Plants and horticulture. Astrophysics. Dog anatomy. Cars. Photography. Electronics. Plumbing. Climate Change. Beer Brewing. Music. The publishing industry. Urban planning. Meteorology. Sports psychology. Business strategy. Fashion. Geopolitics. Philosophy. Insurance.
That certain level of comprehension is - spoiler alert - enough to know I don't understand it, but cognizant enough to have a hunch I’m getting ripped off when the time comes.
Perhaps if there weren’t so many things in the world to understand and be responsible for I’d have the capacity and time to be an expert in what was left.
Or perhaps the lesson in life is to learn to focus on a few things and become an expert, and pay other experts in other fields to take care of understanding the things you no longer need to understand.
If I was to take all the things I have learnt as an adult and inject them into my 21 year old brain I don’t think I would leave the house. Alas, time has a hold of the reins, and death's feet are in the stirrups.
...Add metaphors to that list of thingies above.
