The full A+LDC requires 100 hours for completion. There are 10 courses, each one requiring 10 hours to complete. Each letter in the AGER+LEARNS acronym is referred to as a Decade and the 10 Decades symbolically represent 100 years! 100 hours, 100 years, getting the picture? That's why I am sometimes called the Ten Man, but I prefer Da Decade Dude!
You can find numerous videos on my You Tube Channel that go into extensive detail for how to complete the A+LDC program. Back to how long? It all depends on your time committment. For those with limited time I suggest a starting level of at least 10 minutes a day. If you are blessed with more time available, I recommend at least an hour per day. That's a three month completion schedule. If you have more time you can finish sooner, of course.
In reality, you will never be finished with the program, if you are successful with it. You will be continually monitoring your progress in changing and implementing better lifestyle habits. You may find a new enthusiasm for learning more about health, fitness, happiness, and longevity science that will be with you for the rest of your life. At least that is what I hope!
