I am right there with you. In Cambodia, I was friends with a group of old guys from the US and all four of them were able to treat serious medical conditions by avoiding US "healthcare". One of them had won a years-long battle against cancer right before i met them which he never could have afforded in the US.

Would have died years ago in the US, instead he was sitting around a table eating sushi and drinking beer with friends.

My health problems have largely been dental, and Thailand dentists unequivocally superseded the quality of care in the US for less than 1/3 of the cost at the relatively expensive bangkok clinic, BIDC.

If you ever want info about health care abroad, reach out to me at Travel.

There's some good healthcare info in this post, too.
