Body parts you probably don’t need.

The human body has its own junk drawer: body parts left over from our evolutionary past that we can often live without. Some can cause painful problems, while others are already disappearing, with many people born without them…

1. Appendix: This small pouch attached to the large intestine can become dangerously inflamed and require emergency surgery. Once considered useless, it appears to help support the immune system and store beneficial gut bacteria. But following surgery, you can live a completely normal and healthy life without one. ( The body’s junk drawer. Unfortunately, this one occasionally catches fire… )

2. Gallbladder : This organ stores bile, which helps digest fats. If gallstones cause painful attacks or blockages, it can be removed — and your liver will keep producing bile, allowing digestion to continue without it.

3. Tonsils : These 2 lumps at the back of your throat help catch germs entering through your mouth and nose. But if they become repeatedly infected or grow large enough to interfere with breathing and sleep, doctors may recommend removing them. ( The best thing about that? An prescription for ice cream or freezies! )

4. Wisdom Teeth : Our ancestors needed these extra molars to chew tough, uncooked foods. Today, our jaws often lack room for them, leading to painful impaction, crowding and decay. About 20% of people never develop wisdom teeth at all.

5. Palmaris Longus (Forearm Muscle): This slender muscle may once have helped our ancestors climb trees and swing from branches. Today, up to 25% of people are born without it, and its absence doesn’t appear to affect grip strength. Check your wrist – you might be missing it!

6. Plantaris (Leg Muscle): This small muscle runs down the back of your lower leg and can tear during activity, causing sharp pain known as “tennis leg.” Seven to 16% of people are born without it, though some researchers believe it still contributes to balance and movement.
