The human life span may have finally plateaued. Here's what you can do to optimize your chances for a long life - and what researchers are working on next.

The longevity-boosting heyday is coming to a close as life expectancy gains are nearing a plateau, suggesting strict limits to what medicine can achieve for lifespan.

Lead researcher S. Jay Olshansky warns, 'If somebody tells you that they know how to get you to 100, don’t listen to them; they don’t know what they’re talking about.'

Despite advances in health, estimates suggest only 15% of women and 5% of men may live to 100 in this century, which is a reality check.

Olshansky acknowledges many will live into their 80s and 90s, but insists that reaching 100 isn't feasible for the majority.
