A fact of life
Ageing is a fact of life - we were born young to die old. But while some are lucky enough to live to one hundred or beyond, where does this place the rest of us? Indeed, we would agree that the lifespan of the "average" human is much less. What happens though if someone told you that you are able to extend the years that you are able to live?
