So I am an immigrant, close to 20 years away from my family, I had a similar interaction with my father who passed away from covid a few years back. He was someone who I spoke with on science and politics daily for at-least an hour and remained sharp as ever till his death.

“Should I come back to spend more time with you and the family ?” “Why would you ? Live for the future, contribute, do something new, teach some young kids some politics”

I think that do what’s important to you is excellent advice, it’s not remotely the same for everyone’s family though.
