"I would stick to a traditional FN diet and lifestyle."

But that would mean no guns, skidoos, satellite TV and all those marvels that every one else has.
It would also mean no discussion about minerals in ground, only limiting yourself to hunting, trapping and gathering wood to keep warm ( metal axes are also from European invaders, after all before that they had a stone age culture).

No longer doable in the 21st century.

( I read a long while back that the natives in present northern Ontario were much further sourth, bordering on Lake Superior, that is their 'traditional' land scape.)
