When I look around on youtube trends I get the impression, that living without a Brain at all is pretty common nowadays

"When medical science allows individuals to live with half of brain. It makes sense. Since most of society are already living with half of brains. Take a look at Congress. I betcha all 100 Senators combined only constitute a fully functional brain." -A.H. Roberts

'Totally' in the title made it sound like organs you don't _need_ at all to survive. Brain, lung, liver, and kidney you still need, but you can survive with one/part missing. There are other organs you don't need to survive, like eyes or reproductive organs. You won't be able to see or have kids, but you can live.

i’m currently living with only one kidney and to my surprise i’m doing just fine! life is very normal and besides yearly checkups and ultrasounds, my one kidney has never been a problem.

Also you can lose your bladder, colon, large segments of small intestine, eyes, thyroid (really a large part of the endocrine system) etc. It's crazy how little our body actually needs to continue on. Of course more is better.

I got my left kidney taken out almost two years ago now. It had a tumor i went for 194 lbs to 147lbs in 7 or so months.... If you have this kind of problem text me if you are scared and just don't know what you what to need to know. The short is: don't drink lots of anything at once. Drink more water. Watch how much sugar/alcohol you drink. And watch YouTube videos from trusted sources on this topic. Lastly watch out for those pain kills narco I think. Just try not to sleep on them. The 1st week is the worst after 2 months you are mostly normal. You can live for the most part a normal life. There are people born with only 1 kidney mostly men and usually missing the left.

re:the Liver. You technically donate a "lobe" of it, and can only do so once. the rest just expands to fill that area, really.

If you have the right setup you can live without lungs or a stomach by constantly having oxygenated, nutrition filled blood pumped directly into your bloodstream, then filtered through machine which readministers oxygen and vital nutrients before pumping it back into the body.

You forgot that one down my hallway that my roommate from victorian times got and only plays at 8 P.M. when I'm trying to sleep. I could definitely live without that.

what about thyroid and ovaries? i know many people without thyroids gallbladders or female reproductive organs.🍻

I can at least vouche for the appendix not being a big deal to have removed. But if you dont have a high pain tolerance, if it ruptures its going to hurt, a lot. I felt like my insides were on fire, after 4 days of pain, then trying to play it off my dad took me to a small clinic and they found out it ruptured 4 days prior, he asked if we wanted an ambulance to the neareast hospital. Well it was suppose to be a 30 min surgery in and out no biggie, had a top surgeon doing my surgery and he was confident lol. Took him 3 1/2 hours to fix me, developed gangrene all over my intestines and most of my insides. When i woke from surgery the next day he told me i was quite lucky i came when i did. He said a few more hours and there is nothing he could've done to save me, only give me pain killers till i passed, the gangrene was spread out a lot and it almost got to my lungs and heart, at that point i would've had a week at most to live. If you ever feel lile your insides are literally on fire see a doctor, dont let a high pain tolerance keep you from worrying, like i did.

A few more body parts that you can live without include your eyes, ears, nose, tongue, arms, legs, and sex organs. Not that it would be fun but you can have a full functioning life without any of those. Actually you can lose them all and still be able to live though you would need some serious assistance!
FIRST DRAFT (2 months ago)
My question is that is organs like the liver, kidney and lungs can do 70*% of the work that both could do, then, why do they not work that hard when they're both in the body? Thus increasing productivity and decreasing the chance of failure? No? I'm in no way shape or form qualified in anything to do with medicine, this is just a curious mind pondering... :)

I used to work in an Acupuncture clinic . We had a patient that had half his brain removed. I asked him what symptoms he had, He said when he slept and dreamed he couldn't tell if he was dreaming or awake.

Missing Organ - Large Intestine: I had my entire Large Intestine or Colon removed in 2011. I had Ulcerative Colitis, which is similar to Crohn's Disease. After the Surgery my Small Intestine was routed outside of my Body, near my Belly Button and I had to wear an Ostomy Appliance or Ostomy Bag. Six months after the Surgery, after my body healed, my Small Intestine was plumbed directly to my Rectum and I didn't need to wear the Ostomy Bag anymore. I could then go to the Bathroom like a normal person. I think that Large Intestine should have definitely made the list.
