A closer look

If you thought you permanently evicted those useless lumps of lymphoid tissue when you were seven years old, check your throat again. Tonsils are incredibly resilient immune organs. If a surgeon performs a tonsillectomy but accidentally leaves behind even a microscopic sliver of the organ's tissue, it can regenerate. Over the years, that tiny leftover piece can aggressively multiply and regrow into a fully functioning, infection-prone tonsil, making your childhood suffering completely meaningless.
