I disagree that is has to be this way. I am getting older, but still exploring every day. You do need to keep moving on to green pastures as old ones have been chewed over. In 2021 I'll have lived in 6 cities in 3 countries. I've also been going down the rabbit hole on VR which is fresh technology terrain for me and takes me back to when I was 17 and setting up home networks for the fun and awe of it.
