Welcome back to another episode of the talk. Today we are continuing our conversation with Dr. David Barzolai on longevity.

0:07.6

And, okay, so first of all, we have so many questions, but I wanted to ask you about microplastics, which we kind of touched on in our full episode.

0:16.9

So you mentioned that microplastics are a big thing that we have been ignoring for a long time, but are most certainly causing damage to ourselves, and we've been finding them in a lot of places.

0:27.4

I read that they found like a teaspoon in the brain when people die, a teaspoon of plastic in the brain.

1:16.0

to invest in getting a HEPA filter, which has a certain grade, that's HEPA. It's not one particular company, and I don't endorse
