Hello Hal-9000
For three days now, I have had a pacemaker installed inside my body near the left side of my shoulder above the heart. It makes my heartbeat exactly 60 times a minute. They put it in because my heartbeat was around 20-30 times a minute, which was bad for the organs in the body.
I feel much better now, of course. But an interesting surprise is this: I had "stage 3 kidney failure," but immediately after the pacemaker was put in my body, my kidney function tested as perfectly normal!
So, technically, I'm no longer a human, but an android, since the part of my body that runs my heart is a small internal computer! With a battery in it! With wires attached to two or three places on my actual heart (I can't remember how many). And get this: The battery only has to be replaced every 14 years!
Maybe it's only a matter of time (maybe a few thousand years) when humans will all be total androids with all internal organs installed as, and run by, internal computers!
