“Blood pressure changes, I think, where I basically went straight from a really hot jacuzzi. I was in there for like 30 minutes. I was doing heat stress. [...] and then I went straight into, at the time, it was our pool, it was in February, it was wintertime, and it was 50. It was in the 50s. It was cold. And I was in there, and I was listening to Simon and Garfunkel, I was trying to stay in a long time, get on my cold, and I was trying to impress Dan 'cause he'll stay in there for like 15 minutes. But I started to feel really blinkey, like low blood pressure or something, and I got scared, so I got out, and then I couldn't stand, like I had vertigo or something, and I was so scared.”
