An old woman wanted to commit suicide.
But she didn’t know where the heart is.
So she decided to go to the doctor and ask where her heart is located.
Despite being weirded out by the fact that an elderly woman doesn’t know where her heart is, he obliged and answered her question:
“About three fingers below the left breast.
“Having noted the doctor’s approximate direction, the old woman returned home and promptly shot herself in the knee.”
