Personally, I reckon it'd be pretty, probably if you could take it all and wad it up, it'd probably be a very small little particle that you probably might not even be able to see with the naked eye.

Yeah, I think it's pretty small, personally.

I think there's a lot of unnecessary worry that people have about because they read these things online, they assume they're true. And then they're like, oh my goodness, I'm going to die. I've got plastic in my brain. And it's like, the stress is probably worse than any plastic.

Yeah.

Yes, I remember reading it. I thought it was pretty unlikely to be honest. I was a bit suspicious when I saw the headline.

Was that actually true?

Pyrolysis gas chromatography mass spectrometry.

Which is essentially burning the sample so that you get a smoke coming off, right? So then you've got a gas sample.

So, well, each bunch of lines, so to speak, is sort of like a fingerprint.

The fingerprint of fats is very similar to the fingerprint of polyethylene. They look so similar that it's quite easy to mistake one for the other.

Yes. I think the majority of it. Wow. What's more likely, that I actually have a plastic spoon's worth of plastic in my brain, or there's a measurement issue from a technique that I know has issues with measuring plastics?
