I'm glad for that too.

It does make you think though, you know, sort of, it seems a bit of a shame that things are kind of fixed to the size they were.

Because if you just had like a tiny bit more empty space or a tiny bit less empty space, you could at will change the size of your body from like a three foot tall human, you know, and sometimes I think it would be quite useful to be like poly pocket sized.

Yeah.

And you wouldn't be anywhere near the density of a neutron star for your poly pocket size.

Oh, no.

But it means you could go on a long haul flight, get the cheapest possible seat, and it would be like living in a luxury villa.

Yeah.

Petition for scientists to start working on that immediately.

I think that's where I'm at.

Okay, let's take a break.

And then when we come back, I've got my little story for you.

This episode is brought to you by Cancer Research UK.

It builds on TRACERX, the world's largest cancer evolution study, which tracked lung cancer cells over many years to uncover the disease's earliest warning signs.

Lungvax is designed to train the immune system to spot these signs early on, destroying faulty cells before cancer develops.

Welcome back.

Michael, frankly, I'm astonished that it's taken me this long to tell you about one of the most extraordinary coincidences that has ever happened.

Okay, so in around 2017, 2018, I was working just as a mathematician at UCL.

When you do mathematical modelling,

One of the things that a lot of people spend time making mathematical models of is epidemics, is the spread of disease, right?
