Staying Sharp by Henry Emmons

The authors 9 keys for 'Staying Sharp' are:
Movement, Rest, Nourishment, Curiosity, Flexibility, Optimism, Empathy, Connection, Authenticity
I love the opening paragraph:
Living a long life, a full and joyful life, requires making friends with the passing of time. It also requires a willingness to see that there is always more to discover and more to experience along the way. There is always more to learn.”
