#19 – Adenoids
Adenoids, just like tonsils, are lymphatic tissue that is almost useless. Why did we say almost useless? Well, adenoids are useful to some degree to children because they keep children safe from various bacteria and viruses. However, this lymphatic tissue found at the back of your nose becomes useless when you grow up.
Adenoids just shrink down when you get older and can’t fight off infections or anything like that anymore. Many people get their adenoids removed because they can cause certain health problems, and live perfectly healthy lives without them.
