After a few breathtaking moments of sheer whiteness, the plane pierces the surface of the clouds to reveal the atmosphere above- a seamless gradient of brilliant blue. Joe could feel the bright hot sun on his face as if layers of invisible insulation had been peeled off.

The seatbelt light turns off, and Joe relaxes his grip on his chair.

As he admires the peacefulness of the cloudscape, he thinks to himself,

"I've packed all the medicine I could possibly need. Cipro for food poisoning. Tylenol for headaches, and Advil for pain. Mom also packed travel tabs for dizziness, Sudafed for congestion, and Cepacol for sore throats. Definitely prepared for the worst."

Two hours into the flight, turbulence starts rocking the plane. Moments later, Joe gets a nagging headache and vertigo. Not to mention that the on-flight lunch isn't sitting too well. Luckily he's prepared for stuff like this. Joe smiles confidently at the passenger next to him and reaches forward into the backpack for the pills. A few seconds pass. His smile disappears.

Realizes he had checked them all in.
