I highly recommend her books to anyone interested in animal behavior, real scientific psychology, and heroic effort to overcome adversity.

Kind of like Heidelbergensis. They were among the first to bury their dead, but their immediate past ancestors were like animals and just left their dead behind.
We have a young friend with another form of all this ~ took him 25 years to learn to count but he learned. His ambition is to get a driver's license.
He is as aware of his plight as anyone is ~ and understands his limitations thoroughly. He is exceedingly heroic and works a real man's job ~ redirecting mail in a large office building using a computer.
My kids taught him how to use DOS commands back in the early days. That enabled him to load his own video games. Nothing stopped him after that.
