they have English tutor business with their Thai friend. With low living expense, they do not need to work much as long as they live normal life style. Some couple may like luxury lifestyle so they need to consider to invest larger business. I found that They just want to enjoy their life, relax, and work a little bit. Yes, their children have their own family so they do not need to worry too much.
yes they have children but their children also has their own family. They are going back US once a year during X-mas. Thailand is peaceful and people is very friendly, Thai people love to learn English so they got lots of social attention and acceptance in Thai culture. I think different countries are different culture and local behaviors, so picking the destination is very important.
Thank you Kate. They will stay as long as they can until they need physical assistance. Even Thailand is cheaper, but the medical infrastructure is not good as western countries. The couple said that they will stay until 70.
I think the destination they will choose depends on what they actually like or do after retirement.
