Has anyone studied Machiegenga, Kombai or Mek that have moved to towns and cities and compared their health to those remaining in their indigenous settings? If so, have they noted any differences?

What is your general impression of these people 's health as far as heart attacks / cancer? Does it seem much different from what we experience in western industrialized countries?

Just wanted to say 2 other things.

1) There will always be people who criticize and find fault with whatever you do. Can't avoid it. Personally, I think these studies you are doing are priceless and I would never complain about anyone who eats and uses what they kill. I have rather more negative view of killing for "sport" and making useless things we can do without. Even then, while I might say so, I would still respect their right to their opinion.

2) Last 20 years, can't think of hardly a single show that I got excited about and really looked forward to watching. I think this is one of best shows I have ever seen. Hope you'll do some more similar projects and share them with us. It must make it very hard to maintain a normal family life, though.
