So, we should cut off oxygen, because like everything, it has a beneficial range? I don't mind wearing blue-light-blocking eyeglasses at night, but to wear them all day long is plain stupid. Also, there's the phenomenon called hormesis, which recently shows benefits in the right amounts of even X-ray radiation. So, just like with UV, you should get enough of UV, but not above the upper limit, and should not fall below the lower one either. Same applies to everything including water - too much of it is toxic.

Yes, that was my whole point.
Obviously you can't really reduce oxygen exposure (you can increase it, which is deleterious in high doses), but reduced intake of antioxidants, namely things like methionine and certain vitamins, absolutely does lead to faster degradation of the body. Note: there isn't conclusive evidence more antioxidants is better, just that deficits are definitely bad.
