I have come to notice that oxygen is used in medicine (hyperbaric chamber) to support fast recovery of bone's fractures, wounds and even cancer.
Moreover, according some studies and publications insects were bigger in the far past of our planet due to the increse percentage of oxygen at about 30%
My questions are:
- May we definitevely say as a fact ascertained by science that oxygen has the power to heal people?
- What was, in recorded history, the maximum length of time a person has spent in enriched oxygen enviroment and what are the conclusions reported after the experiment?
