Testing my limits with air inflation- I plug up and barely let myself deflate for the next twenty minutes. The goal is to stretch until it's hard to breathe. I finally get to the breaking point, and you can hear me softly gasping for most of the video as I grow visibly bigger and bigger. While I didn't measure, this is surely the biggest I've been since I was younger. I guess that means I have to go for another round and try to beat it!
