Tai chi and getting some energy back

It is said that we are born with a finite amount of energy and that is all we have to make it through life. As life progresses that supply of energy is depleted through living: events, act, thoughts, points of view. It takes energy to live. Less of our original life force becomes available to us as we age. It becomes stuck, tucked away, or wasted upon others. We can get much of it back, however. If you knew this were possible, would you consider doing what it would take to get it back?
