Two hundred years ago, only 30% of people lived long enough to reach 50. By 2050, life expectancy is predicted to be 100 years on average. Today in the US, the federal government spends $350 billion, or 3.5% of the gross domestic product (GDP), on healthcare for the elderly population. That will double in just two decades. Medical science can extend your time in the ICU on a ventilator for the last 30 days of your life. Studies have shown that some of the biggest expenditure for health care occurs in this last thirty days of life. However, this is not the vision of old age that we want for our relatives and ourselves! Rather, antiaging medicine seeks to extend and improve the quality of life.
