Most cheeses you put on a sandwich here in Estonia aren’t aged very long at all. The ones you eat as a snack are.

Also some people who think they are lactose intolerant, will still get diarrhoea from lactose free dairy products. These people actually have milk protein allergies I suspect. Because some of those people also can’t eat wheat products.

My ex is one. Milk, aged cheese or just plain white bread. Or even ducking pasta. All make her shit violently.
