And that can be a problem for some people where if in later years they put on a little bit of weight, and I don't mean just a little bit, I mean like 20 kilos, carrying a 20 kilo backpack is hard and you notice it straight away.

But if it's distributed to your whole body, you can then end up setting yourself up for later diseases.

But getting back to your question, have I answered your question, which is that the weight is still the same, it's just easily better distributed so you don't feel it?

What do you do up there in the mines?

You're not a train driver, are you?

Wow.

And how much water would you go through?

Wow.

And is the Pilbara the place where there are traffic lights in the ocean, in the sea for the ships to come in and out on?

I remember seeing that in one part of Western Australia when I was travelling up there.

Not on the roads.

Isn't that weird?

Traffic lights in the ocean but not on the roads.

It's a different world.

lose their mind as well oh that's so annoying when you're going through a tunnel as well so i mentioned earlier that you've got these little radios in your phone and there's a special radio for picking up the signal from the gps satellites and that's not going to go in a tunnel but in the cars they've got different degrees of smarts and they've also got gyroscopes

that measure whether you're turning left or right and speeding up and slowing down.

And so they'll estimate where you would be and they know what the tunnel is.

And so in some cases they just say, no, I'm not picking up anything, but if the car's got a few more smarts, it'll say you're here, but it's not actually measuring it from the satellites, it's just estimating it.

That's the first thing.

The second thing is that with the radio, you didn't generally lose radio in the tunnels, but in some of the tunnels...
