Feels like this is a totally different topic.

What if: Neuroplasticity allows you to build new base cognitive tools from sensory information, or dump/change existing tools. If you build sufficiently numerous, broad, and adaptive tools when you are young, you will be able to do many, many things when you are older.

Still might have challenges learning new languages, or say to dance if you never learned how to dance at all, at the same rate as a toddler, tho.

Maybe compared to a toddler, but this person I am talking about became a programmer at 65 after being a physicist and then a biologist. I know more old people like that from the university. I really don't think age is so much of an issue that it should us stop from prolonging life. I really want these brilliant people to have more time on Earth. And I want more time too, even if I can't learn anything new at all past 125. Life is beautiful.
