Eli5: Why can broken bodies (aka corpses) not be ‘fixed’ like machines?

2.26K views

If a machine breaks, you can fix it, even if it means replacing a part, and you can do this AFTER it’s stopped working. You can replace a part in a body to, like an organ, but only BEFORE the body stops working. Why is this? What do we lose when we die that cannot be replenished (except in the seconds/minutes after death in certain circumstances)?

Every starts falling apart. The blood vessels and veins lose integrity, cells stop reproducing, bacteria suddenly have nothing to stop them from just consuming all of it. The brain is the main player, and it rots. There’s no way to fix the deterioration of the brain. Even seconds after death, there’s been too much damage to the brain, and we have no way at all to fix something that complicated.
