And I can see advantages or disadvantages to that.

And I'll stop right there.

Good question, Dr Carl.

You're obviously talking about that movie, The Ten Commandments and Moses, where in the Bible, Exodus 7, verses 10 to 12, it says Aaron cast down his rod before Pharaoh...

and before his serpents, and it became a snake.

So Aaron or Moses threw his, he had a rod, right?

He had a stick, you know, like a walking stick, and he threw it down on the ground in front of the Pharaoh and it turned into a snake.

And then the Pharaoh says, okay, you can take all your Jewish mates with you and get out of Egypt and the Red Sea and all that sort of stuff.

And that's related to the heart.

Imagine a snake.

So we're coming to the heart in humans.

Imagine a snake as being a long skinny balloon and you fill it full of water.

Lying on the ground, it looks like a snake.

Hang it vertically and everything pools to the bottom.

So if you've got a snake that lives in the water, the heart is sort of roughly in the middle of the body.

And if you've got a snake that lives on land, it's closer to the head

Because by gravity, you'll have removal of blood from the brain.

So it's just that fraction closer to the top of the head.

So that way, it can keep the blood flowing to the head.

And the way that Moses did it was this is an old trick.
