 I don't know anyone who's used one. I know. On the plane, there's a bag there. As a kid, I was always like, am I going to need this, or what's going on here? Was it like motion sickness, like not diagnosed until the 80s? I don't know. My mom, I think in the 60s or 70s, was on a flight, and this woman is like ill and just leans over.
