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)?

Look at it this way:

On an engine, you shut the car off before doing any repairs for your own safety. The car is now “dead”

You then do the repair, and you can start the engine.

With humans, we can EASILY swap parts while the engine is off (dead)

The problem is, we haven’t found the key to turn the engine back on yet.

So when a Dr does a transplant, it’s like changing parts on a engine while it’s running.

Once the engines off, we don’t know how to restart it.
