Whether the result of wear, tear, and exhaustion of resources or whether genetically programmed, all life has a finite span and each species has its own particular longevity. For human beings, this would appear to be approximately 100 to 110 years. This means that even were it possible to prevent or cure every disease that carries people off before the ravages of senescence do, virtually no one would live beyond a century or a bit more.
