Yeah, that was a bit scary.

They divide the microplastics into two groups, depending on the dimensions of them.

I was concerned, was I eating a lot of microplastics?

And it turned out that the higher levels I had were actually the smaller ones that you get through your lungs, which probably means having lived a life in London...

You know, six decades in London probably wasn't very good for getting all this dust and things in there.

That was a bit of a worry.

That's probably because I cycle around London a lot in the last 30 years.

I still cycle.

I don't like wearing a mask.

I know I sort of probably should.

And I've put a new water filter in my home to take out some of these chemicals and at least some of those plastics.

I'm still not totally convinced.

on how bad they are.

And the science, I don't think really we've resolved that issue yet.

But it's something I'm looking at closely.
