1. Astronauts wear diapers.
Well technically it's called a "Maximum Absorbency Garment" but for all intents and purposes it's... a diaper. See, missions are generally pretty unpredictable and might have a bunch of delays. And when you can't just unbuckle and pop on the toilet, you have to make like a baby and let loose. Unconfirmed, but we're pretty sure astronauts change their own diapers.
While we here at Zorpads are certainly not qualified to tell you how to hypnotize your lover or stand in for a really good couples therapist, there's one situation we're uniquely able to provide advice on: smelly feet.
