People Living Hundreds Of Years (Haidut)?

Maybe spending most of one's time inside a place where the CO2 levels are much higher than normal. A totally sealed house, for example. That's probably the most effective strategy other than living at a high altitude. I wonder what's the percentage at which CO2 in the air becomes toxic, if that's even possible.

I heard that even the most aired room is much more toxic compared to being outside (next to a road with busy traffic)...all due to constant evaporation from furniture ,walls , cooking...

Hum.. I wonder if that's why I feel significantly better when I spend some time in the garden.
