What a nice, old-timey, image that is! :-)
Please read “Flood Your Body With Oxygen” by Ed McCabe. You can find it on Amazon. Oxygen therapy is used all over the world but the US doesn’t like it because of the Pharmacy Corporations. Just like they go against the herbalists. We have a holistic doctor in Anchorage that does ozone therapy so I know they must have them all over the US if they have them here. Prayers for your father and blessings for his life.
