I don’t get ice cream headaches but my throat “freezes” sometimes. Does that count?
I don’t eat ice cream, but sometimes my brain freezes anyway, often in mid-thought. And then things slip my mind.
I never heard of an ice cream headache, until dating my wife. She gets them, and at least two of your kids get them. The rest of us don’t. Most who witness would claim that I’m a professional. Perhaps I have head calluses.
