Smoking grandmother and air quality issues

My great-great-Grandmother was a member of an Indian nation.  She lived off the land and hunted for her food. She would tell lots of stories to my grandmother about it, and as such, my grandma told me those stories too. I plan on telling them to my children and grandchildren as well. Grandmother would tell us about the huts they would use in wintertime, plus the teepees that had become their house in the months when they were traveling to hunt, fish, plus grow food. I listen to the stories with great enjoyment but to be honest, I don’t know if I could survive those days with the hot sun and no air conditioner. In the winters, they had to bundle up. There was no heating system.  All of us have become so accustomed to our comfortable surroundings plus the perfect air. We probably would have succumbed long before that Indian nation.  Their air purifying system was a hole cut in the top of their little hut. They didn’t have any technology at all. I am so spoiled now I guess. The Heating, Ventilation, plus A/C system has become an integral part of our lives for more than just heating plus cooling It also can rid the air of all smells plus contaminants. Heating, Ventilation, plus A/C systems and thermostats are wonderful inventions.  It makes me wonder if our great great Grandparents ever wished for some way to heat and cool their teepees and huts. If only they had access to today’s technology. They would be living like kings.
