Okay.
And I think that it's a very important point because I have gone through so many ethics committees to shine long wavelength light.
to do various things, including on people that they've got problems and they've got sight problems, they're patients.
We've actually also done it with children.
And we've got through ethics committees really with very, very little comment because on many of the ethics committees, they're physicists and they understand the issue.
Yeah.
And then beyond 900 is infrared.
Right.
So we've got the near infrared and we've got the infrared.
Now, you're right.
We've got to start kind of – we've got to start –
defining these terms a little bit more clearly.
But I think for nearly all of the research we're talking about, we're talking about where vision stops, which is around 700, and we're talking about the near infrared, which is, for practical purposes, is going up to around 900.
But, you know, I remember doing an experiment with UV once, and it was an experiment, bizarre experiment, trying to work out if a reindeer could see
UV light.
Do they?
Yeah, they do actually.
But then while we were doing the experiment, I was beginning to say, look, I'm not believing any of this data because I can see this flashing now.
And as it was pointed out to me, you will see wavelengths of light that you shouldn't see if you just turn the energy up.
So if I put you in a room with UV and I pump loads of energy into that UV, you'll see things that you shouldn't.
