Today’s Gratitude
Evolutionary psychologist Geoffrey Miller's Tweet is worth considering, repeatedly:
How many of these ancestors are there? Well . . . just move up your family tree 20 generations and you will find more than one million great great great . . . grandparents.

This is one of the many cases where facts are more amazing than any fiction you could ever concoct.
I've long been fascinated by this thought experiment. Imagine driving along the highway passing your chronologically arranged ancestors, all standing in a line. What would that be like?
