Every creature that had ever breathed oxygen, dies. That's a 100% mortality rate.

Every creature that hadn't breathed oxygen also dies. Can't live with it can't live without it.

Damn you got me, was hoping no one mentioned the immortal jellyfishes. Though if you think about it eventually when the planet dies they'll die as well

Your body is essentially an oxidation reaction that it ponders its place in the universe.

That's poetry. Nicely done.

Yes. Oxygen does degrade our bodies. Unfortunately, we also need it to stay alive. Life be like that.

It's reported that many people who have died had varying amounts of oxygen in their bloodstream at the time of death.

Oh yeah, reactive oxygen species, right? But iirc those are only confined to certain parts of the cell

Rust on the Myrtle Beach ferris wheel has also been shown to reduce fertility levels of crabs nearby, causing a dramatic drop in their population and California Bill 34 was passed to drastically limit how many can be caught, devastating the local fisheries!

For more information, Google "Rust ferris crab rule 34"

HOW DARE YOU BAD MOUTH RUST LIKE THAT! Rust is natural, and isn't anything bad. Let your body rust, and accept it's warm embrace.

Be sure to drink plenty of Coke to dissolve the rust your body builds up from breathing!

I had one of those local boutique sodas the other day and their coke knockoff was nasty. Tasted like old grandma candy.

Check the label. Anything with sulfuric and phosphoric acid is good for rust removal. The reason why it's in cola is simply because without it, it would be way too sweet from all the sugar.

Isn't it the opposite? Soda would be bitter AF cause of the caffeine and the carbonic acid is added to give it the fizz, then they dump a ton of high fructose corn syrup in.

1

The carbonic acid is for the fizz, yeah. The sulfuric and phosphoric acids are to regulate sweetness. Sodas are syrups that get diluted with water hence the need for all that sugar.

No, it's too sweet because big soda brands are targeting Americans first and Americans just love too much sugar in all foods. There are plenty of non American sodas in Europe and they have only a fraction of sweetness.

Interesting, what's a common one that the average person would consider good?

1

Dalston's is amazing and is available in every supermarket in the UK. No sugar, no sweeteners, just carbonate fruit juice with some flavouring. One of my favourites.

Fentimans is a big soda brand and they do add sweeteners, but their drinks are nowhere as sweet as Coke etc.

Seriously, though, when those blue-green fuckers came up with oxygenic photosynthesis and started shitting oxygen all over the place they killed practically everything else on the planet, the bastards. Paleontologists call it the Oxygen Catastrophe or Oxygen Holocaust.

Jeez man this oxygen addiction is too great cant withstand 30 seconds without oxygen

That's just lack of creativity from your part.

The OP didn't say the composition of the pedestal, if it has cavities, its temperature...

It won't float away if you freeze it first, of course it will sublimate away but not all at once.

Edit: Melts, doesn't sublimate, still won't melt all at once though.

2

Good point, though it still won't melt all at once though it takes time to melt and boil (not much time but still takes time).

Yeah it's why we have antioxidants. The idea is oxygen is constantly stealing electrons from nearby molecules and antioxidants help replace those electrons.

Life is just a constant form of slow death. Up until your body simply can't replace the old cells fast enough anymore.

This may be a good source for it: https://www.goodreads.com/book/show/25663961-how-not-to-die

The book is about food, but mostly it talks about oxidation of the body and how various foods affect that, because that seems to be the main factor for aging and other degradation of the body. (TL;dr: eat a lot of broccoli)

I'm not an expert though, so cannot judge how accurately the science is presented

2

It's true. The medical field over the last few decades has curbed when to give patients high flow concentrated oxygen for this reason.

6

That's why breathing pure oxygen is bad idea

10

I've also heard that electrons in them cannot be relied upon - especially to be anywhere that they say they will (instead, they zip off to the other side of the whole galaxy/universe, then before you can tell anyone they're gone, they are back again!) :-P.

Sodium is a dangerous explosive, choride is a poisonous gas, yet we put the mixture of two into our food.

Raise awareness of sodium-cloride!

Oxygen is one of the most reactive gases. It can burn iron at 100°C.

8

It can burn diamond at 720 °C, what do you think it'll do to soft tissue over the course of an entire lifetime. Things helping aerobic life survive are
a) partially consisting of partially oxidized polymers in the form of carbohydrates (remember, the only thing that cannot burn is what has already been burned);
b) oxygen's peculiar, natural triplet state which greatly slows down its kinetics compared e.g. to its horrible relative, ozone.

I thought this will somehow relate to rust programming language

What oxygen does to your lungs is what Rust does to your brain

Oxidative stress is a major factor in health and longevity. People who stop breathing oxygen before dieing generally live a bigger proportion of their lives healthy on average.

Linking to this got me permanently banned from the entire Libera IRC network, apparently because a random snowflake mod also happened to be named Walter and decided it was a personal attack.

It's true my friend works with it and their hair went blue

Oxygen is one of the key components of dihydrogen monoxide, and we all know how dangerous that stuff can be.

3
lemmy.world

Wait until they hear about a particularly nasty form of oxygen, dihydrogen monoxide.

I prefer the IUPAC name: Oxidane. Terrible stuff, it's even used as an industrial solvent and yet we are exposed to it every single day of our lives!

Oxygen toxicity is an iatrogenic illness caused by exposure to high FIO2 during oxygen therapy. Oxygen saturation should be monitored in patients receiving supplemental O2. As the oxygen gets metabolized, some molecules convert to superoxide anions known as hydroxyl radicals, which are human tissue toxic. The resulting pathophysiological changes at the alveolar level result in decreases in lung compliance, diffusing capacity, and PaO2 levels. Central nervous system (CNS) toxicity can occur with exposure to high partial pressures of oxygen. Acute changes in the lungs resulting from oxygen toxicity consist of alveolar and interstitial edema, alveolar hemorrhages, and proteinaceous exudates. Further prolonged exposure to oxygen leads to a proliferative phase, which includes the proliferation of type II epithelial cells and fibroblasts, followed by collagen deposits. Exposure to FIO2s greater than 0.60 for as little as 24 to 48 hours can lead to severe irreversible pulmonary fibrosis.[6][7]
