Like PS said, if your friend is savvy she can make her own decisions.
But ask your friend to consider the following:
She’s 82 now and loves traveling. How many more years can she travel and enjoy herself? Can she enjoy her $2 million house while she’s away or will it sit empty collecting dust? Costing her gardening and maintenance?
When she’s 90+ will she care to live in such a big house?
I’m 38 and I’ve been humbled and learned a lot being around elderly people. They appreciate living life and being with friends and family. They enjoy sharing wisdom. Most old people I know have no interest in supporting a large home that they have to maintain and be prisoners of.
In my auntie’s example she has no interest in consumption like young career-minded people. She hates restaurants but she appreciates good healthy home cooked food such as chicken vegetable aloe vera soup, or salad with blueberries and pine nuts. I’m happy that she can now travel and meet relatives, old friends from school, and make new friends and expand her horizons.
