Assume human lifespan is now 150-200 years: how differently would people treat the first 50 years of life? What does education and choosing what to learn change with that much extra life?

A lot depends on what other enhancements we get to ourselves during that same time.

I don't think we'll be able to reverse aging without learning enough about ourselves to make lots of other modifications. At the very least, imagine pulling your brain plasticity back to 4-year-old levels and learning more languages.

What does learning multiple languages have to do with brain plasticity?

The first couple years of life are the critical window for acquiring language, and it gradually gets harder as you age.
