I can get you to see 150 if I just turn the energy up a bit and you see these little red glows.

Yeah.

Let's take two pieces of information first.

So one of the main theories of aging is the mitochondrial theory of aging.

Mitochondria regulate the pace of aging.

So if you can regulate mitochondrial health, you can regulate aging.

That's relatively clear.

So that's the first thing.

And then the second thing to remember is that there's more mitochondria in your retina than there is in any other part of your body.

Your retina has got the highest metabolic rate in the body.

Age is fast.

And my argument always is it's the sports car.

Bangs out of the garage, but after so many thousand miles, you've got to service it, otherwise it falls apart.

So there was a very strong argument for trying to manipulate mitochondria in the retina, which is great for me because I'm a retinal person.

I'm a visual person.

So I had the tools to do it.

So

The first experiment we did, which was very gratifying, was to actually measure people's ability to see colours.

Now, we used a rather sophisticated test, first of all.
