I think people get dumber as they age. I feel like I'm probably dumber than me 10 years ago. No one wants to admit it, but I sense it in myself and I think I can see it in other people. I feel like peak brain is probably like 22 years old if we are being honest. Yeah you might still be doing dumb kid stuff but you are at the age where you just have this energizer bunny inside. You can just go to the library and churn multiple all day and night sessions. Sleep in one day and perfectly recovered. I "know" more now but I'm definitely slower than when I was younger.

Would be great if we didn't spend so much time faffing in school on stupid stuff and got into our strides in our career maybe 5-10 years earlier. When I think about my first research job, that could have probably been done in middle school vs undergrad. Wasn't really any more challenging than when I worked part time in a restaurant in terms of the tasks. I probably could have been working on some thesis under an advisor for my hs years instead of being stretched thin over the boilerplate curriculum. And then I probably could enter the workforce at 18 and have enough to get up to speed on the job pretty fast. By 22 I'd be in management right at the peak of my mental faculties and skill buildup.
