Why do you think most Asians live long lives?

at the contrary, i think that the asian will live less longer, because the western industry are delocalized in Asia, bringing work, but more especially pollution,

And that the working conditions are less supervised in Asia, that they are in occident

actually, the chineses can to hope to live up to 71 years, in occident food up to 100 years, is not rare

I do know that there are some health problems that can affect certain nationalities more than others even living in similar conditons in the same country.

Ethnic minorities here in the UK for example, black people, Asians, are more prone to certain health problems than whites are, generally speaking.
