You should make a surgery mod where you have a new bar on top of your health bar, called the hygiene bar, and when you spawn in a fresh world, its full, but when you step on dirty blocks, like clay or something, your hygiene bar gets low, and when its empty, you have blindness for 5 seconds, and you spit out player meat, which you can pick up. You regain hygiene by putting your player meat back in. You have a time limit of 10 mins to get surgery. If you don't, eventually you'll lose health and die. So then you craft a surgery bed, (a green bed) and sleep on it. Another player will put you to sleep using a sleepy potion, and then they will get a medical cutter and right click on the player, which will open up their body. Then all they have to do is shift click all the player meat in, and then grab a sewer (which needs to be refilled with stitches every time used), and right click with it to sew their body up. Then you hit them to wake them up. But be careful, if you hit them while their body is not sewed, they will die instantly (and you will too!) !!!
