A children's story: There was a woman who got a wish and wished for eternal life. However, as she got older she began to shrink like people do. They get shorter and wrinkle up. The older she got the smaller and more wrinkled she got. Eventually she was the size of a thumb and looked like a raisin.
Thereafter she determined that she was going to invent a "live forever spray" and spray it on me so that I would live forever. However, some years later she announced that she was probably never going to invent that spray, and that I would, in fact, die. Thus far this has been my closest brush with immortality.
