Did you know that you could (in theory) survive with a loss of approximately 45% of your body’s mass?
You could have a reasonably normal life without one of your lungs, a Kidney, your Appendix, Spleen, Tonsils, Adenoids, Gall bladder, the Fibula bones from each leg, 6 of your Ribs and some of your Lymph nodes.
It is quite survivable to remove your Uterus, Ovaries and Breasts, your Testicles and Prostrate – although these would lead to disruptions in the Endocrine system, giving rise to the need for hormone therapies to avoid long-term problems such as brittle bones.
If you allow (for the purpose of this article) these of artificial replacements, your Stomach, Colon, Pancreas, Salivary glands, Thyroid, Bladder and your other Kidney could all be replaced.
Theoretically surgeons could remove your Eyes, Ears, Nose, Larynx, Tongue, Lower spine, Rectum and all your limbs.
In an intensive care unit they could also remove your Skull, Heart and remaining Lung – replacing their function by use of life support machines, at least for a short while.
This adds up to a theoretically survivable loss of 45% of your total body mass. But any trauma that destroyed all these organs would undoubtably be fatal, even if only from blood loss.
Surgically removing them one at a time over many months would likely also be fatal, due to infections in your immune-compromised state.
