People think that the immune system is like this pinpoint accurate machine that kills invaders. In reality, it is more like a carpet bomber that functions under the principle that we can heal and viruses/bacteria cannot. Inflammation is basically your body carpet bombing and healing.
We would also not be able to build muscle mass as the repair of microtears is what leads to hypertrophy.
So we would all be dead. Healing if fundamental to life.
