I was the same as you undecided. I got some great advice on this group and decided to do it myself. I entered Thailand on a Non O 90 day visa . Everything just fell into place, it's really not that difficult. Immigration are more than willing to help.
Absolutely correct. I'm 65 a fitness fanatic gym, walking,and a healthy diet. This might not be a surprise to you but I am not in need of any medication whatsoever.๐
It also might be worthwhile mentioning that depending on your age Health insurance in Thailand can be extremely expensive. Check out the costs before you choose what visa to get.
