I actually thought about this a few years ago, is it possible that we age because of oxidation to some degree? Is there a way to prevent that? I thought about it, how blood can rust and just had the connecting thought but I'm not smart enough to know if there's any actual correlation.
Edit: Got some really cool responses out of this to think about, thank you everyone!
I'm no expert but I'm fairly sure that is basically true in a way. As per zr0's top-level comment. Forms of life that can make do with less cellular respiration, for example by using external sources to regulate temperature (cold- blooded), don't need to invite as much oxygen into their cells, and so they get less weird damage over time.
Mammals in general have not adopted this strategy. -

ooh, then I must have gotten the terms wrong...
What I was thinking were the free radicals that are generated during basically most oxygen related reactions in the body, I thought that was called oxidation (at least, in terms of the body).
So, you know anything about how (or if) antioxidants are used against free radicals?
That actually depends on the type of antioxidant. The body has certain innate antioxidants (e.g. enzymes like catalase) to deal with reactive oxygen species but antioxidants that you get through your diet are also very important in that system (like vitamin c and e to prevent oxidation of cell membranes for example). Also some phytochemicals (like polyphenols) can act as an antioxidant.

Oxidation is how red blood cells collect oxygen to pass to the rest of the body. In fact it is iron in hemoglobin that "rusts" to collect the oxygen. You would die if your blood didn't "rust".
Antioxidants have nothing to do with this.
Thanks, this is an unexpected image and a fun fact for the next party.

Pretty sure oxidation plays a major role in aging, but can't tell you the exact mechanism, I have no idea about it.
But about the blood rust idea, I don't think that can work, cause we don't have just iron particles that can directly interact with oxygen just floating around in our blood, we have a complex (I.e. hemoglobin) that contains significant amounts of iron, which somehow makes it really good for binding to and carrying oxygen.
Deviating a bit, carbon monoxide poisoning is really akin to suffcation iirc, cause it binds and occupies the hemoglobin, effectively reducing the amount of oxygen that can be carried by your blood.
However, do fact check me, I might be wrong about something...
Edit: BTW, it seems that "oxidation" might not be the right term to use here, so do understand that I am referring to free radicals here.

Oxygen (especially as free radicals) is damaging to pretty much all your tissues, so your body moves it around in little bodyguard proteins (hemoglobin). These each contain 4 small iron molecules as part of the much bigger structure and doesn't rust or function like iron in any way. The iron is mostly used for electrons (and also damages your body if it's not inside the hemoglobin and causes more aging)
Carbon monoxide has a higher affinity for hemoglobin than oxygen, so it sticks to your blood cells and makes them useless for hours. Super dangerous.
Point being "oxidative stress" is bad for you and a major cause of aging that your body tries to fight. If your body doesn't fix this well, you age faster. If it repairs damage too well, you're more prone to cancer. Just wear and tear of using your body.
So to the original question of can this process be stopped... Absolutely! Hold your breath - the oxygen will stop coursing through your body and you will stop aging. Just ten minutes is enough to end aging indefinitely! Then you have to worry about other problems like body decomposition, but the oxidative stress will be cured!

Look at what it did to the Linux kernel too.

Or an extremely deadly poison. Or an explosive, flammable gas.

Carbon monoxide, not dioxide.

Did you see what oxygen did to the Hindenburg? I'm not going to let that happen to me. Say no to big oxygen!

To sum up - because I taught this to a kid yesterday - for a period, basically all life photosynthesized and oxygen was toxic to most living things. There were large growths of photosynthetic Cyanobacteria that pumped the air full of oxygen. Living things at the time (like, bacteria and microbes, nowhere near vertebrates) couldn’t handle all the O2 and died.
Iron had been taking in most of the oxygen, but it got all rusted up. There’s beautiful geological evidence of this.

Have you ever seen asbestos catch fire? Me neither. So it's your choice what you'd prefer breathing in.

you train your legs and arms and back, but when i train my lungs im told smoking isnt allowed in the restaurant
