I also have met with Andreas Moritz , though we had to drive an extra 200 miles with our motorhome on our way to Florida. A motorhome is easy we stayed in a campground in the next town over from his office.
For general information you could read his book Timeless Secrets of Health and Rejuvenation http://www.ener-chi.com
I was 67 at that time and was always tired my whole life.I used amphetamines for 40 years for energy, several anti-depressants for 15 years, high bloodpressure medication, compounded hormone replacements therapy and high cholesterol medication.
I am 70 now and off all medication and can run on my own energy. Last year I hired a personal trainer to keep my body in the best shape I can.
If I have any questions I pay for a telephone consultation with him.
