Get the young guys to do the lifting, there’s still plenty of room for old guys with experience who know all the tips, tricks and gotchyas.

Edit: Fair point, you don’t want to be entering a trade which requires heavy lifting as an older guy with no experience.

If you are 40 making a career change you have no experience tips or tricks.

When you lose your white collar job to AI you don’t have those tips, tricks, and gotchas for whatever work is left for you.

To be an old guy with experience you need to start as a young guy.
