This is an interesting article (from OSU Research News) about the costs of managing failing health caused by aging. The personal costs (financial and otherwise) are tremendous. This is exactly the sort of thing that younger people try very hard not to think about. You should be thinking about this, however. This is your future unless we all band together to help change it! While the article focuses on health insurance, the real way to minimize the costs of aging is the development and introduction of widespread, low-cost anti-aging medicine.
