From 30-47 I have only found it easier to learn new skills. I’m 47 now and even in the last 10 years, I learned a lot. Like, how to build a full stack web app which I’ve used with our customers for a few years, to deliver millions per year in sales. I became an expert on at least a dozen programming tech acronyms to get that done. Also, I learned 2D/3D mechanical CAD design, I learned circuit design and PCB layout (fusion 360/solid works/eagle, etc), and I became fairly fluent in Mandarin including some literacy with hundreds of characters. I was naturally interested in those areas because it helped my business and directly improved my life to learn them, but I still had to force myself to continue and I think everyone does at some point. Of course, this is all anecdotal, but I don’t expect age related decline should be happening for most people at age 30 unless there’s some underlying physical health issues.
