You know, the mutations of DNA are occurring really when you've got very, very high levels, not when you've got

relatively low levels.

And Richard's work has been terribly interesting because he's dug out all the little corners, all the little things that you think about three days late.

He's dug out all those little corners.

And things like aborigines in Australia don't get skin cancer.

white people there probably are in the wrong place given their evolutionary stage.

Richard Weller is very interesting.

I think he said he hasn't got any dermatological friends anymore.

Probably not.

But he also pointed out that if skin cancer was directly related with sunlight, then we should find in skin cancer patients very high levels of vitamin D. In actual fact, they've got relatively low levels of vitamin D. So as you say, that story needs to be unpacked.

And what's happened, I think, in the dermatological literature

is that we've followed a pattern.

Yeah, we've followed an assumption.

And it's gone a very long way down the line.

And then it's taken a little bit of a rogue to come out and say, hang on, we need to take a step back here.

And I think Richard Weller's leading that.

And...

We obviously both have an interest in daylight, but his interest in daylight tends to be focused a little bit more on those blue short wavelengths, whereas I'm at the other end of the spectrum.

But I think he's a mover and a shaker.

Yeah.
