But after that, it was used by the scientific and research community as an example of a thing to stop.
This is kind of why a lot of us, myself included, get into science.
When we see things happening, we have the drive to explore them, understand what's happening, and then try and prevent the next case from going on.
So the Haldane saw these cases.
JBS Haldane's father saw these cases and then used that to start researching diving in a more controlled way.
So now decompression sickness is extremely preventable.
I hope not.
Somewhere down there are wooden caisson shells in which people worked until they literally died.
And I think that's incredibly powerful in terms of remembering the context of where our society comes from and how it's been built.
Right.
Air is roughly 21% oxygen.
So since oxygen can become toxic, when you elevate the pressure, the 21% oxygen becomes toxic if you're diving deeper than about 200 feet below the surface of the ocean.
Our bodies use oxygen because it's extremely chemically reactive.
Oxygen is one of these weird molecules that sits on the periodic table in a location that just makes it react with everything.
We take advantage of this to build fires.
That's why oxygen is needed for fires.
We take advantage of this to design explosives.
That's how we design explosives.
And our body internally produces energy using oxygen in pathways that are not terribly dissimilar.
So what happens when you have too much oxygen is essentially that volatility turns against us.
