How Many Retire Early - Low Income

How many people have retired early on very small income? If so, how much and what country?

I've heard of a lot of people retiring after 20 years in the military, to somewhere like the Philippines, Vietnam or Thailand. Mil retirement is pretty small, just curious how bad things have gotten over the past 5 years for you.

I do not have a ton of savings. I can retire at 50 in 9 years, will get around $3000 a month, that doesn't include anything for healthcare, but somewhere like Thailand actually has decent healthcare that isn't crazy expensive. I am planning on living with less than $3000 a month and putting anything I can into savings and then pulling SS at 62.

My grandfather was extremely healthy up until his death at 72, I don't want to work until I'm in my 60's and get a whole 10 years of peace, I'd like more, even if I have to live a simple life.
