#42: Just Be Gross

Most people can agree that air travel is no longer an enjoyable experience. Unless you fly first class, airlines squash you into rows of tiny seats like a bunch of sardines. Any space to spread out is high-value real estate. There’s no place more sought after than the armrest. If you ever find yourself in a silent battle with the person sitting next to you, try this approach.

Cough into your elbow and then put your arm back on that armrest. We guarantee that your adversary will give up the fight. No one wants their arm touching a stranger’s arm that’s full of nasty germs. This hack is pretty gross, so only use it when the armrest situation is really dire.
