1. Oxygen bar = freaking ridiculous. Standing around Trees, plants, shrubs, and grass in the morning = free.

2. Radicals doesn't have to be just from O2. Radicals are highly reactive though. In fact, they cause the same reactions that destroy the Ozone. Yep, a single molecule of CFC (chlorofluorocarbons) radical can react thousands of O3 molecules, because the reaction is propagated continuosly.

Antioxidants halt this propagation step. Wine, Pomegranate juice, and I think olives and apples too have alot of antioxidants. Look at the Italians and Greeks, they drink lots of wine, that's why they have a lot of old people.

Your body will try to maintain itself (by repair and replenishment of cells). When your body start losing this ability, then that's called "aging". One way to slow aging is through antioxidants.
