Why Is Harman's Theory Wrong

Throughout this chapter, the key idea was death. The beginning of the chapter starts with a little Greek mythology and the idea that fate and death can bring even the strongest man to their knees because death is controlled by fate. Death and fate are linked together and can describe the deaths in different species of animals. In a tragic story, the Trogan Tithonus asked Zeus to grant him immortality but did not specify eternal youth, which prolonged his lifespan but not his heath, resulting in begging for death. Many humans have ultimately asked eternal youth and immortality without diseases but that would break the law of physics. The maximum amount of years that a human can live is about 120 years. Back in the late 1800s, a French biologist, Charles Brown Séquard even injected himself with a serum that he extracted from the dog testicles and guinea pigs, thinking that he could achieve immortality. About 12,000 different physicians tried to create an elixir that would prevent death but none were successful. Cyanobacteria, a blue-green bacterium, is one

Harman’s theory states that the amount of damage in the molecules will increase in age while the antioxidants will slow down the damage to prolong life. It was first established that his theory was just wrong but if the theory was in a more subtler form, it would broadly be correct. The first part was that lifespan depends on the number of free-radicals that is leaked. The faster the leak can mean a shorter life span. I found this very interesting because I never knew why some species lived longer and why there are certain family that die around the same age. The free radical leak theory of Harman seemed very understandable. The smaller the creature would mean that the animal has a shorter life span due to their metabolic rate, cardiovascular flutter, increase in oxygen, and a higher amount of free-radical
