We all fill a unique role in life. We all make a unique contribution to our family, or profession, our work, our community, the world. If we do not fulfill that contribution, nobody else will. Some may cover parts of it but no one will make our unique contribution. By analogy, every cell in he body has a function. If we lose it, no other cell fills that need. We may compensate to a degree but something is lost. Dec29,2010
