That's the real one?
8:29
So, so let, let's, let's c- let's caveat that just a little bit.
8:32
So there was a cougar at my grandparents' place, and so my cousin, my brother, and I were out, uh, whittling spears, talking about how we were gonna take on this cougar with our pocket knives.
8:43
And so the three of us on the side of the hill, uh, standing next to a big rock, carving the spears, and as we're carving these spears, I have this vivid memory, and this is clear.
8:53
Vivid memory of that cougar coming over the crest of the hill, coming at us.
8:58
And at this point, I absolutely panic.

The limbic system takes over.

Which solo thing that you do takes the most skill?
6:14
Probably the world's fastest juggling in terms of speed, dexterity, precision.
6:19
It's the most juggling catches in one minute.
6:22
And that was one of my moonshot records I set early on.
6:26
And the first time I tried to break it, it was 422 catches in a minute.
6:30
I currently hold the record at 586 catches in a minute.
6:33
That's almost 10 per second.
