I was 60 and hubby (slightly younger) when we learned TTATT. We are third gen with no family who have left except my daughter. We got caught in the financial crash at the same time as loosing our religion. It was NOT easy but we have started our entire lives over. We are SO GLAD to be out from under the weight of the WTBT$ !
I know 80 is much different than 60 but I guess my point is: when people are ready they will leave. If not, they won't.
If the 80 yo doesn't find TTATT on their own it would not be kind to tell it to them.
