On the second day of my dig I worked next to a dear woman who was probably in her 80s.(I didn’t think it would be polite to ask her age!) She has been coming on digs for seven years. Having a knee replacement didn’t stop her - she just kneels on her good knee.  She said, 'I realized I’d rather be outside than inside doing housework. I can’t get any of my friends or family to join me, but being out here, digging for fossils … I couldn’t be happier if I won the lottery!’
