I started using Head and Shoulders ten years ago for itchy scalp and dandruff, and then for ten years I have not had itchy scalp and dandruff, so I thought "why do I still buy shampoo to combat itchy scalp and dandruff when I do not have itchy scalp and dandruff," so I stopped buying the shampoo for itchy scalp and dandruff and can you guess I have now? Can you predict what currently afflicts me? It's alright if you can't because apparently I fuckin couldn't either
Cutting something out of your life because you think you don't need it any more only to realize that it was in fact working as intended and preventing a problem that will return should you stop doing this is a good experiment to run periodically with something small like dandruff shampoo, lest you start to think it would be a good idea to do this with like let's say public health and the social safety net and vaccines
