That seems illogical given all the serious food and water borne diseases, generally poor personal hygenics, dirty utensils, everything that moves or grows is edible diet of Asia. I haven't been there in 20+ years, but my arms would stick to the tables at restaurants, no napkins were ever offered, Watching Chinese chewing up bone-in fowl, bone-in fish, shell-on seafood and spitting the refuse on the table beside their plates was as normal to see as a Westerner wiping their hands and mouths with napkins. Waiters/Waitresses pick up the dishes and wipe away the refuse with a nasty rag, ready for the next customer. Dishes and silverware being washed in the same lukewarm gray water that washed the last 300 dishes. You've never had food poisoning until you have had it in Asia. No, China can't possibly have a longer life expectancy. I think China is promoting fake data.
