I've been cleaning out my files and found the following:
Two years ago a 61 year old hippo, Tanga, died in Munich's zoo during a
heat wave.
When she was 50 her daughter, Rosa, birthed a healthy baby.  Tanga was so
taken by this event that she spontaneously began to produce milk and nursed
the baby along with its mother!     I wonder if that will happen to some of
us when our grandchildren are born!
