Have you got health insurance covered? 1 tip if you're not aware is if you are covered by a broker/company in the USA and you need urgent medical treatment and the hospital cannot contact the insurer due to office hours you may have problems. Im not sure how common this kind of thing is but I can only go on stories Ive heard and those are not direct stories, just 3rd hand.
The reason Im conversing with you is because Im planning on a possible retirement and have some concerns about certain things also and Id be loathed to think Id been paying for something like health insurance only to find out I was never covered!
