Our world, like us, is constantly changing and evolving, which is a good thing, but I feel that as our world gets more complicated with the use of all this artificial intelligence, smartphones, computers, etc., we may lose who we really are. I am all for looking ahead and not looking back; however, there are certain good points to us looking back which will centre us in the here and now. And that is remembering who we are, where we came from and having that good old-fashioned common sense that we seem to have lost along the way. This book is going to remind you that there is so much more to us than you think. Science is discovering new things about us all the time, how we think, interact and how we make sense of our world.
