["So, I've been practicing holding my breath for a few months now.", 'For what? Are you a diver or something?', 'Nope. Just a regular Joe-Schmo that wants to break a world record. Never felt so prepared.']
Oh, well good luck. Have you heard of Wim Hof? He's like a world record breath holder and he does it in freezing temperatures too.
In a few hours, I am going to try and break the world record at holding my breath. I have been practicing for months.
