I work in nursing in an environment that tends to be richer in oxygen due to constantly working oxygen tubes and vents as well as the tendency for unused o2 valves to be left on. I’ve had a theory for a while that the reason so many nurses in their 50’s look as young as they do is due to the increased oxygen in the environment.....it’s a pet theory and given that folks often say that I don’t look my age, I’ll just stick with that story!
I don’t drink my tap water, but instead drink a bottled water than contains more oxygen.
It’s amazing.
