I have pain everywhere. Just because I'm not twenty anymore doesn't mean my body gets to just give in. I know I could help more with that issue, but I feel like my design should be more automatically durable.

Murderers

"Honestly our appendixes try to kill us too often. Something ain’t right with it." ~ moonbarrow

The Nerve

"The sciatic nerve routing. Going through the periformis muscle was a bad idea." ~ Sleepdprived

"Just FYI: actually passing through the muscle is an anatomical variant. For the majority of people, the nerve just travels alongside the muscle. Still, that variant is a... uh, pain in the butt." ~ EauEwe

"I'm currently experiencing sciatica right now. It's a nerve being pinched by your spine or muscle in the lower back. The best way I can explain is like a scalpel scraping off your bone marrow throughout your entire leg 24/7."

"It's physically and mentally excruciating so much so that people who suffer from it would rather have their entire leg amputated than live through it. And the thing is this is not an uncommon medical condition. Since the cause is usually a spinal injury, it takes way longer to recover than other injuries, so you're pretty much sleep deprived and exhausted from the pain at every moment until it resides. I'm 25 right now and my first sciatic episode started when I was 21" ~ psyatica

Jaws

"Teeth, one set while we're a child, one set for 60/70 years." ~ godca_grema

"Meanwhile sharks, the lucky bastards, just keep growing new teeth." ~ XxsquirrelxX

"We used to call my brother Shark Boy growing up. That dude had LAYERS of teeth. He had one tooth that grew in the roof of his mouth."

"He also had teeth growing sideways in his gums which torqued his other teeth. It took 2.5 years to get him prepped for orthodontics and then he was in braces for another 5 years after that. Worth it though, he looks like a Colgate commercial now." ~ justuselotion

Too Loud

"The ear. Eyes have eyelids, you can close your mouth, but if there’s an extremely loud noise, your ear drum has to just take it and be irreversibly ruined." ~ sicknessandpurgatory

"Well technically there is a muscle that can tighten your ear to prevent damage from extreme noise, it’s the same reason you don’t hear yourself chew. Some new cars will make a sound to trigger this muscle to prevent hearing loss from the noise of an accident." ~ engineer_doc

Heeled

"Achilles tendon. Single point of vulnerability that has no bone sheath and will absolutely cripple you if it's f**ked with." ~ Torvaun

Why do we have an appendix? And why is it a ticking time bomb? All good questions.

SIT!

"A bony butt! It actually hurts to sit still." ~ thatluckyfox

Exposed

"The elbow. Why the f**k is there a nerve that's so exposed, when you hit it at just the right spot it sends a jolt down your arm?!" ~ hikoboshi_sama

"It’s not just one nerve. You’re talking about the brachial plexus. It’s a bundle of nerves that come from your spine and innervates all the muscles in your arm. That’s why stingers hurt so much, it’s taking out every nerve."

"It’s also a good site for nerve blocks when you have upper limb surgery because you can disable the arm and reduce post operative pain by applying anaesthesia around the nerve roots. Also, in the case of brachial plexus avulsions, you lose all function permanently. And on that note, nerve injuries are freaking crap. We should be able to regenerate them more easily and quickly." ~ ShibuRigged

Cardboard

"Knees are a good idea, but needed a bit more R&D before being rolled out." ~ ChampionshipMission

"Came here to say this. Have you ever seen a child try to make a spaceship or a suit of armor out of cardboard, but they don't have enough cardboard and none of the pieces really fit together anyway, so they end up lashing it together with dozens of strips of tape at every possible angle until it just barely holds together? That's knees. That's how your knees are made." ~ DerCatzefragger

Tiny Humans

"Having sharpened rocks that slowly push their way through the sensitive gums of tiny humans who are too small to understand or explain the reason for their incessant crying. Bonus bad points for these tiny humans being designed to get 100% of their nutrition by latching their new razor teeth around the nipples of another human." ~ PoetryOfLogicalIdeas

E is for Empty

"Bowels. I should be able to decide when to empty them completely! In one go and not little bit now and more later!"

"Edit: All this fibre talk, I get it. I now understand more about the importance of fibre. But that kinda adds to what I'm saying. Imagine not needing a summoning ritual. Like deciding when you do and don't drop the kids off at the pool. A human eject button." ~ J1ra1y4

The bowels, they never let up. And like I said earlier, the knees have it. Ankles, knees, elbows, the keys to a happy life.
