I don't think it is all about age.
Those who went through difficult, we expected loss of job, people, or major parts of their lives are most likely to decide they don't want to go through that again. The more they are hurt, the more likely, and more significantly they will change in some way(s).
People will not stop traveling, but how & where will likely change.
People who never did things on line before, have discovered it IS possible, and besides the safety issue there is a major time savings. A lady staying with me during this has decided she is making major changes to how she does her business because she estimates on-lineing a lot of it will free 10 hrs a week. Other businesses that never bought into remote work are seeing it can work in many cases.
That may allow a LOT of people to escape the big cities for better cost of living, climate, etc. so we may see some de-urbanization.
Nursing schools are seeing a lot of student questioning if they want to return to nusing--they never factored in the life threatening issues of the career.
Where these will go, I have no idea.
