This is a special book for everyone who wants to keep their minds and brain alert and full of life. This book is just a resource for those who want to try some brain games, physical exercise and leisure activities that would or might stimulate your brain to keep you alert and on the ball. Remember, before starting any physical exercise program you need to discuss it with your doctor no matter how old you are for your own safety and health. Dieting does help when you need to lose those extra pounds that you don't want. Check with your doctor to make sure that the program you start is the right one for you. I DID! This book includes great research done by many prominent doctors in the field of Alzheimer's and dementia. There are many studies that I sited and several that I feel will help not only seniors but young adults and even kids understand the importance of keeping active, reading, writing, doing puzzles and other activities that will keep you out of your chair and active outside and inside.
