It really depends what you mean by survive.
You could do ECMO and dialysis and get rid of the heart, lungs and kidneys, parenteral nutrition to feed via an IV so no need for a gut.
The patient would be bed bound and at immediate risk of dying from a complication but in theory that’s basically an empty abdominal cavity connected to a brain and a bunch of machines.
You would need enough decent sized blood vessels left to connect it all up but otherwise not much physically.
A wet fart is a slightly more polite way to say shit yourself.
Basically if there is poo in your undies after a fart it was a wet day.
Yup, you need to send it back to them but for a few quid (or included if you have their replacement head subscription) they will change the battery for you.
We have recently gotten ourselves some SURI toothbrushes and they are eco friendly, repairable, the heads are recyclable/ biodegradable. They also give a better clean than my old oral b electric. Quieter too. Highly recommend.
Maybe, you’d want to talk to someone like an intensive care doctor really but yeah a lot of your organs can be replaced mechanically these days at least for a while.
