Lemme expand: There would be no limit to how much people can do. The greatest minds would become greater, and some of them might abuse that kind of power. People would become more and more arrogant and prideful because they would feel that they could live forever. There would be no limit, no end destination and suicides might go up. People who wait for death would seek it out instead of waiting for it to go up. And the population would increase drastically, causing overpopulation and the necessity for only one child per household laws and stuff like that, and birth control and abortions would be necessary.
