It was in November, December, so they weren't getting much daylight.

They were in a rather, yeah, they were in a situation like all people are in Northern Europe.

And then we had a problem.

It was Christmas.

experiment ended.

But let's think about this.

These people not only had more significant improvement than they would get with red light, the effect lasted much longer.

Now, one of the things that makes me think now, I go back, I go back and I think about our experimental results.

Why did I get such good experimental results?

in whatever it was I was doing?

Is it simply because I am drawing my subjects from a population of human beings who are living under LED lights?

If I went and did those same experiments on a group of pharmacists,

you know, or people who are doing surveying of the countryside, would I get the same effect?

I think that in the built environment, we are suffering from a suppression of our physiology.

I have to be careful here about not going over the top, but we're suffering from a suppression of our physiology via mitochondria that is just being produced by the built environment.

And

A point that I really need to make here, because I now spend a lot of time talking to architects.

I spend more time talking to architects than I do talking to ophthalmologists or medics.

You put a building up, invariably the majority of the phases of that building will go over budget.

It's rare for a building to come in under budget.
