Everyone dies.
"Everyone dies."
Oh, dear. Yes, you're right, but not everyone dies from being bled to death by leeches. There was no science used to justify the leech treatments on Washington. It was just what doctors did at the time for things like strokes, heart problems, and almost everything else. They did it because doctors had been doing it, on faith, for a long, long time.
Then science stepped in and explained some of the intricacies of the human body. Leeching stopped for the reason that it did no good and often a lot of harm.
Science. You may have heard of it.
Besides, I thought you were planning to live forever.
Death, where is thy sting? Grave, where thy victory?
All that stuff.
