Is the retirement visa the best option for healthy 80 year olds applying from their home country, and do they need international health insurance?

The discussion centers around whether a retirement visa is suitable for two healthy 80-year-olds and the requirements for applying from their home country. It was noted that for the NON-O visa, there is no insurance requirement, whereas the NON-OA visa does require proof of international health insurance. The commenters suggest checking the specific requirements on the Thai embassy website in their home country.
