Interesting scientific essay about human immortality.
From the moment of birth, we begin the battle against death - against the inevitable. Statistics say that a newborn child can expect to live an average of 76 years. But averages may not be what they use to be. In 1786, life expectancy was 24 years. A hundred years later it doubled to 48. Right now, it's 76.
Immortality is the concept of living for a potentially infinite, or indeterminate, length of time. Throughout history, many humans have had the desire to live forever. What form an unending human life would take, or whether it's even possible, has been the subject of much speculation, fantasy, and debate.
