Downside of longevity (Score 1)

My Father just had his 100th birthday, he retired 35 years ago. We age at an exponential rate with our probability of dying doubling roughly every 8 years. As an exercise I calculated how long we would live if we aged linearly. Our lifespan would be in the order of 3000 yrs. This would mean we would be old for a very long time. Your 90's could last hundreds of years. This might not be so much fun. When the retirement was set at 65, it was the mean life expectancy, this is now close to 80 which means we will more old people who will be older for longer. Slowing human ageing is not a panacea
