They have found ways to navigate life with their disabilities. It's heartbreaking to read one story where the woman's condition gets worse as time goes by despite her best efforts to navigate life with her disabilities, but in another story it's truly encouraging to read how another woman manages to live a full life despite her disabilities. In fact, she even manages to use her experience to help out similar patients deal with their challenges. It's fascinating to read how a musician who has lost the ability to read musical notes can rely on her/his muscle memory and his/her ears to play a piece of music. It's heartwarming to read how other people around the patient have helped them navigate life.
But seriously, imagine for a while that you've lost the ability to recognize daily items. You go to a supermarket and then suddenly you realize you can't read the labels anymore and you can't even be sure if what you're looking at is an apple or an orange. You pick up the newspaper and you feel that what you see is written in Martian language. How would you feel? What would you do?
All in all, even though I haven't finished reading the book, I HIGHLY recommend it.
