You think Iam a caveman still living under a rock ?
I don't for 1 second think hospitals share patient records outside of their own organization, hence my assumption there IS a medical record database in Thailand rings fairly accurate as far as iam concerned nor do I believe an insurance company requests records from every hospital in the world when a claim is filed.
As for how much I spend every month or how much is in my bank accounts.
I get paid on the first of every month, 80% is transferred to my home country, both accounts (Thai and home country) have their balance reduced to zero the same day.
I have zero money in the bank and other than my credit cards... it is impossible to know how much I spend each month.
