>Sleeping well, eating well and exercising does work. Science about this is well-established. So why arent we?

Those will give you at best another marginal decade. By all means worth doing but its not radical life extension. At the same time a young body can take lack of sleep and can physically perform even if not exercising much better than an old one. So there's more to it than just lifestyle.

Those will give you an entire life. Living while being healthy is an entirely different life than surviving while being unhealthy.

I would say it gives you +25 years of healthy lifespan.

Compare it to being obese, wich can happen very young and is in part determined by how you are fed when you are a baby/child.
