David: Can you get a heart murmur from a lack of sleep? Because I have not slept since we've got here and I think my body is shutting down.
Alexis: Well, I hate to admit it, but I actually know very little about heart murmurs.
David: Well, I have one. Uh, the pulse is very irregular.
Alexis: Honestly, David, I have tried to find my pulse like a thousand times and nothing. So don't worry about it.
David: No, this is very serious! My heart has not rested in a long time, my immune system is very low, I have not been able to find kale anywhere here.
