Well, if you don't want 'em anyhow, no loss there.
And instead of having to explain why you don't want 'em to people who refuse to get it (and refuse to comprehend that it's not their business to begin with), you have a handy excuse.

The carsick one is interesting. Inner ear damage? It's an unexpected side effect. I take it that roller-coaster rides would be right out, too.
The one that entertains me is my father's sequela: he now sneezes every time the light hits him strongly.
It just really amuses me, for some reason.
To the point that these days, he sneezes and then immediately rolls his eyes at me and tells me to go ahead and laugh, he knows I want to.
But it's just so funny.
And it's another odd one, that doesn't seem to have a rhyme or reason.
