Wolf – Sorry to burst your inferiority complex bubble, but I am very science oriented and you aren’t correct. An addiction is something craved by the body which the body doesn’t need and more often than not is harmful to the body. It starts with a psychological craving and can end up being a physical one. O2 doesn’t qualify in this definition.
As a side note those whom frequent oxygen bars could possibly become psychologically attached to the oxygen there. That oxygen is for kicks, not to maintain homeostasis!
