Yes, it's true, that Eskimos are not American Indians. The Eskimos are living in 3 continents: North America (Canada and USA), Asia Russia and Europe (if we count Greenland as European place, because it's a Danish territory; if it was up to me, I'll count it as another continent.
I know it's not that big as it looks on most of the maps, but I think it's big enough -- for instance it's bigger than the country Mexico.)
The Eskimos are yellow, Asian people. Indians are also somehow related to Asia as origin, but they are earlier migrants, so their outlook, languages and cultures are not so obviously Asian. But, still, the ones in Alaska look more Asian than the ones around the Amazon (South America), for example.
It's 'natural' for the neighbors to have problems and even hatred. I often meet similar cases as yours The lady would set you straight rather quickly that...
A young man from Scotland was very against my conclusion that "You're almost an Englishman." /From outside Scotland, England... Great Britain looks something pretty 'equal' and united, but from their internal point of view, they're very different nations and even some of them want independence. Another case -- a Chinese was upset, that living in neighboring to the Koreas region (full of Korean minority), there are people, who ask him is he a Korean and that he looks Korean... There are even cases when some native Chinese, who live in Taiwan, Hongkong, Macao, Singapore and so on, prefer to refer to themselves as Taiwanese, Hongkongers/Hongkongese, etc., but not 'Chinese'./I expressed before my point of view, that it's better, if people pay less attention to the nationality and the world become more cosmopolitan. Many people like to separate themselves: for example our nation against another nation. If there is no another nation, then it will be our province against another province or our sport team against your sport team. One of the most terrible forms is our religion against your religion or our race against your race (at least the history shows so). Back to Alaska -- it's really a place with many minorities and it's bigger than what people usually imagine -- maybe you know this picture, so I'll show it for the others, who never imagined the real size of that state:

It's very natural in so big territory to exist more than 1-2 minorities/nationalities, because there isn't so cold as in Antarctica.
Except the Eskimos there is another Asian (with Asian origin, look and culture) minority in the USA -- the Hawaiians. They're relatives of most of those in the Philippines, Malaysia, Indonesia and other countries. So, we can say that the most Asian native US citizens are the Eskimos and the Hawaiians (and after them -- the American Indians, which are an earlier Asian 'wave', something like 'proto-Asians'). There are similar ethnogeneses and minorities in Europe, too. For example the one and only 100% yellow, Asian and Mongol minority in Europe are the Kalmyks, living in the European part of Russia (more about this minority:
https://en.wikipedia.org/wiki/Kalmyk_people). This is the only Mongol minority in Europe.
I'm sorry, if it was boring for some of the others, but I think Mojo likes to read, plus it's useful for the forum (from the 'more quality content' point of view).
About the diseases -- yes, some of them are inevitable (unavoidable), but washing reducing the hazards; for example some of the diseases are known as 'the disease of dirty hands'. I don't want to concretize which ones, because it may sounds 'racist' (which is not), but I know some minorities, who do not like to use water very much (for example they rare take a bath/take a shower) or they just haven't enough water around... and there the disease rate is much higher.
What I mean and what I want to say is that better hygiene isn't a panacea (it's not 100% effective), but makes sense, because can reduce the number of the ill people. And I think we all agree about it. What we can call 'American national drink'? Is there something, except the Coca Cola/Pepsi Cola that's pretty popular or something that's not very popular abroad, but people like it (something like that cactus wine, for example)? Do you like to make home-made drinks?
