my grandmother is the second oldest of six sisters and a brother, and she's a very short woman. several of her younger sisters are a bit taller than her, and my mother is pretty tall. I was also a very tall child. this led me to believe that when getting old, people actually "shrunk", and eventually disappeared. this was a short lived-belief: my uncle was very tall, and I went to his funeral.
