Renowned Arsenic and Lead Specialist

So this was maybe nine months after the fire in Notre Dame, and I had been struck visually by the fire, the yellow smoke, which is a telltale indicator of lead. The fact that 400 tons of lead constituted the covering of the roof of the cathedral. And a lot of that had volatilized, presumably, but no one really knew how much. So that got me thinking, and I happened to be in Paris at the time, so I thought if it's so much lead, could it be that it affected the population living within say a kilometer of the cathedral? I thought there wasn't really a lot of clear information about what had happened, and what had been measured. I thought some more openness and transparency was needed.

So while there is no kind of one size fits all story, there are plenty of times when...kind of like clusters of activity. And some kids don't come out as trans. They come out as wanting to begin a process of exploration around gender, wanting to sort of bend things a little bit or begin to present themselves in slightly different ways without a concrete cross-identification.
