The quote is from Lazarus Long, Robert Heinlein's fictional character, who by the way was over 2500 years old when he uttered it. In the future, humans will live longer, more productive lives. Healthy old people will be quite able to work for a living and will not need an old age pension. They also will spend a fraction as much on preventive measures as the reactive measures (coronary bypass surgery, nursing home care, etc.) that we spend now. If you don't want to live a longer, healthier life, that's your personal choice. However, I have a lot of things left to do and need at least another 50 years to do them. I was an early adherent to radical life extension therapies and have spent over $80,000 on them over the past 27 years. If they work on me like they work on lab rats, I'll have that additional 50 years.
