Based on conservative assumptions for health care improvement through 2065, demographics researchers Ron Lee and S. Tuljapurkar, cited in a Census report, project average lifespans to reach 88 for women and 83 for men.
by 2050, the average human lifespan in developed countries could easily reach 140. Many of the areas of research that are already underway today, including nanobots that could enter the bloodstream, promise to eradicate diseases, improve treatments for cancers, and counteract the chemical changes that lead to aging.
Living to 140? For those still around (or at least their descendants) after the peak oil/genocidal holy wars of the next few years?
