Yes, my own words, but the worst of a cold and the worst of food poisoning (what OP compared the mild covid to) are, IMO totally different. The former is an inconvenience (headache, a bit tired, constantly runny nose), the latter is a totally debilitating state of never-ending vomiting and/or diarrhea. If you told me I was about to get a cold I would shrug, if you told me I was about to get food poisoning I would be dreading it.

There's no way we're going to come to a resolution of this discussion without additional data given our evidently very different experiences of what a cold is. All I can find is sources saying that colds are usually mild. But since this also called "mild covid", that resolves nothing.
