Each year when I come back it is a culture shock to me. Overweight/obese people all over America, it is nothing like that in SEA at all. What is very interesting and I don't know the reason but maybe someone here can chime in.... I am not talking about Asia just SEA but you have heavy people in Thailand, Laos, Cambodia, East- Timor, Philippines , Malaysia, etc etc of course here in Viet Nam too but rare, I don't know the reason for this....
