You are never too old to set another goal or to dream a new dream.
-- C.S. Lewis
I tell you the truth, unless you change and become like little children, you will never enter the kingdom of heaven.
Children are full of dreams and curiosity. They are always learning, discovering new things, and expanding their view of the world. The amazing thing is that acting like a child by dreaming and learning can actually keep you young. Aging is inevitable, but getting old is a choice. My uncle John knew this intuitively. He learned to surf when he was in his seventies, and never passed a chance to ride a roller coaster through his eighties. He was in fact "younger" than most people in their thirties. Science is just now catching up to what Jesus, CS Lewis, and my uncle John already knew. Brain scans and health studies have shown that continued learning, goal setting, and a sense of purpose can act as a firewall against many age related illnesses. So the saying "you are never too old", should really be "you don't have to be old".
