The worst reason for retiring overseas would be
The worst reason for retiring overseas would be moving to another place and wanting it to be like home, because sometimes things do not work the same way as they do back home.
For example, the work ethic here in Panama is different from the work ethic back home, where I'm from, in the US. Here in Panama, if you want to have internet connection in your house, you would not get it by just asking for it. You have to make an extra effort. After I applied for an internet connection, I waited for a month, but they had not done anything. So when I got the opportunity, I parked my car in a way that one of their company vehicles could not escape and asked them to give me the internet connection I applied for a month ago. I am not a bad guy; I just need the internet. So if you decide to live overseas, you have to be ready to do things differently because sometimes if you do things the proper way, it just doesn’t work.
