When I was a child, I had the bizarre belief that when I was sick, I could be cured by eating onion rings. I don't know how I came up with that. My mother tried to talk me out of it, but usually after I kept insisting it would work, she would get me some onion rings (maybe just to demonstrate that it didn't work?). Most of the time I felt better after eating them. I'm sure it was all in my head.
But the weird part is that even now that I am an adult, this still usually works. I know how absurd it is, and that actually, eating onion rings when I am sick should make me sicker or at least have no effect, but it still works. Is it some kind of psychosomatic voodoo?
