Well exactly! As you say, the vast majority of people are not going to want to live some wacky, insecure, nomadic lifestyle when they are 65+. Fuck that for a game of soldiers. I'll keep my financial security, my savings pot, and my home ta! As I said, I can go travelling/on holiday whenever I want to. I really don't see what the OP is talking about as 'living the dream' at all.
I think she - and the few posters cheering her on - have been watching too many programmes with Jane McDonald on her cruises, and shows about celebrities travelling around; like Bradley Walsh and his son, and Prunella Scales and Tim West, and the 'bros together' things like Gino, Gordon, and Fred, the Grand Tour with Jeremy Clarkson and his mates, and Travel Man with Richard Ayoade.
Lots of travelling and experiencing different cultures is wonderful and exciting and really opens your mind, and is good for the soul.
But not when you've got fuck-all to come back to when the money runs out, and it's all over. (Not even a home!)
As I said, it's best left as a fantasy!
