From the video transcript emphasis, mine:

Um you know we we toss around these uh terms like thousand year event um and it makes it sound like well okay it was just really bad luck that’s not what it means.

When we say this was a Thousand-Year event um means we shouldn’t have witnessed it if we lived for a thousand years.

Um Methuselah of biblical fame should not have witnessed an event of this sort um the only reason we’re witnessing itis because it’s no longer a thousand years uh event it’s maybe a five or ten year event…

I’ll leave it to the readers to further discuss the idiocy of the Mann’s quote above.

Incidentally I live in Fort Lauderdale. It rained a lot.
