Two other economical areas need to be mentioned to complete the economic picture of a greater life span. These are taxation and insurance. Although it may seem strange, if people continued to work until the latter age, tax, with all its complexities would surprisingly be unaffected. Any government, regardless of it political convictions would be taking in the contributions in similar percentages as before. Statistically speaking, it would make no difference.
Insurance is another matter.
As far as life insurance was concerned, the companies would have a virtual field day. The mere fact that human beings could live to a ripe old age of 100 would mean that contributions would span over a longer period of time. Payments due to death would still be at the same average rate. That is until the government stepped in with new legislation to curtail abuse. By and large, and provided good health prevailed, living to be 100 should enrich a nation and its population.
