You really need to think twice before retiring to Thailand.
First spend 6 months here, to lose your rose tinted glasses before burning your boats.
Life here is not the bed of roses dreamed by tourists.
The visa will be a big problem. Border runs are being squeezed out.
If your pension would be enough to start with, inflation will eat it away.
And if you meet a tough period, do you have enough to meet extra bills ?
Go and visit state hospitals to see what you can expect. It's a far cry from the sleek private ones.
Thailand is not kind to penniless expats.
