'100 Days' will last a person 100 years. Full of valuable information, it will take much longer than 100 days to incorporate. A friend and I did the 100-day program and found this only long enough to skim the surface. Now on my second go-through of the program, I am taking a month to do each of Yudelove's weekly exercises. This book is a basic text for anyone interested in understanding and practicing qigong - or anyone who wants to know how energy influences the body, mind and health. Highly recommended.
This might be agood book if you know exactly know what you are doing. Trying to do energy exercises week after week without any control from a teacher is just proposterous, and will get you into a mental institution. Some exercises are very advanced and might cause disfunction in your mental state and your sex life. So, i advise you to be careful.
