So the antioxidants in food, I actually, it took me a lot of work to do this math, but I calculated the concentration levels of antioxidants in the most popularly cited antioxidant-based foods, and they don't have the sufficient concentration to really make a difference.

I did the math for a while they were at pressure, and I don't remember the exact number off the top of my head, but it was something like 180 bottles of Merlot per breath that the diver would have to drink in order for the antioxidants to have an actual effect in neutralizing the oxygen.

Don't get me wrong.

I'm going to eat dark chocolate and blueberries forever, hopefully.

But I'm not convinced that there's enough of the chemical substance in them to actually make a difference.

There are two major differences.

The first is that we don't have to worry about some of the things that we do on land, such as shrapnel and burns, because the density of the water slows down a lot of those effects before they can reach more than a meter or two.

The other big difference is that we have to worry a lot more about the shockwave.

In air, the shockwave decreases very quickly, but in water, just like sound, it travels a lot more readily.

And so imagine how far away you can hear whale sounds.

You can hear whale sounds for miles and miles.

The same type of impact where the density of water moves these waveforms along more efficiently than in air occurs with the shockwave from explosions.

So you see different injury patterns from the underwater explosives, but most of them tend to be internal, which is kind of terrifying.

It's just the physics of the shock wave.

It's even more sci-fi than just a standard impact.

So they don't carry with them a lot of force.

So the actual force from a shockwave is not very strong.

But what happens is you go from zero pressure around or whatever ambient pressure you're at to the highest level of the shockwave and it happens in zero seconds.

The metaphor I like to use is a car.

Imagine you're in a car, you're at a full stop, and then all of a sudden you're going 60 miles an hour with zero acceleration.
