Health is a natural outcome of Yoga. Yoga makes your body vibrant, flexible, leaner, pain free and increases immune resistance power, giving your body chances to deter diseases and improve overall metabolism.
Imagine what it would be like to have the same quality of life at age 70 that you have had at age 30. Yoga enhances the overall efficiency of your body and cellular functions, so that the body deterioration associated with the aging process is greatly reduced. As a result, you can enjoy your life no matter what age you are numerically. Age is just a number after all.
