As the title says, this little book is both practical and simple. Much of what we think we forgot we have, in fact, never really remembered. The author gives useful tips on how to learn a name, a parking spot, the location of your keys, or whatever you have trouble remembering and imprint it in your brain. Often, we think we have a problem with our memory, but the underlying issue is stress, lack of sleep, poor eating habits, or other issues that we need to resolve before we can improve our memory. The book also includes suggestions for recalling past memories and for avoiding getting lost when you travel.
This book isn't designed to make you a memory wizard; it's designed to help with practical issues most of us face regularly: losing your keys, forgetting what you went into a room to do, not remembering names. It does just what it was designed to do.
