How does ozone effect the blood?

Ozone shortens the life of any cell it encounters, this is especially hard on red blood cells. Ozone (and other powerful oxidants) is produced by white blood cells when fighting infection. Ozone converts "good cholesterol" into "bad cholesterol"... which tends to cause hardening of the arteries. Ozone does not have any long term "healing" powers to cure AIDS and such... if it does not kill directly, the body does not learn "secrets" from ozone having killed an invader.
