The limit on oxygen intake is set by the hemoglobin content of your blood. Given normal lung function, increasing the amount of oxygen in the atmosphere will have little effect if the hemoglobin level remains the same.
Not that it means much anyhow, only 20-25% of the oxygen in the blood is actually delivered to tissue. About 3% of the remainder will be exhaled at your next breath due to the partial pressue of the diastolic phase, the rest will be recirculated.
It's not lack of oxygen that's responsible for diseased cells.
If that makes sense! lol
No. lol
Our body's were created to live forever, before the curse of death. In all actuality, cells with extreme amounts of pressurized oxygen applied to them, act in their original course, maintaining all livelihood to the body.
And that would kill the idea of cancer too.
Cancer is a disease, and disease didn't come into the world, according to the accounts in Genesis, until after Adams' sin.
