A life expectancy of 80 or 90 where you are active until the last six months of your life is a win compared to keeling over at 55 from a stroke or heart attack. The fact that life expectancy is not 100 or 1,000 doesn't mean that it's not worth investing in improving quality of life and life expectancy. What happens when we get good at treating dementia is that your children will be able to have intelligent conversations with their great great grandparents (or you will be able to have intelligent conversations with your great great grandchildren).
