Just need a question answered after reading an article. Questions are —–″There are obvious biological limits to life span. Despite being spared from a multitude of lethal agents (e.g., Tuberculosis) that were present a century ago, we find ourselves up against other factors that can end our lives. With people striving to find the proverbial “fountain of youth”, what evidence does scientific research show are two possible ways to delay death and extend maximum lifespan? Why and how do scientists believe these two biological paths help slow down aging?
