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)?
In: Biology
It comes down to the brain. We can make (manufacture) parts to fix a machine. We can even replace most parts in a human body. But we don’t know how to grow a brain or replace (transplant) one brain for another. The connections are too many and too complicated. Once the brain loses oxygen, the tiny parts of it (cells) start to die. We don’t know how to create a living cell. We don’t know how the brain stores our memories or information. In many ways medicine is in its infancy.
