The document summarizes key findings from the Prevention Index, which ranks 50 countries on their ability to support healthy aging. The top 10 countries account for only 1.1% of the global population. There are significant gaps between the top and bottom countries in life expectancy (24 years), healthy life expectancy (21 years), and working life expectancy (23 years). Countries that spend more on preventative healthcare and have better access to doctors tend to rank higher on the Index. Diet and exercise are challenges hampering progress for all countries. The UK could rank first in healthy life expectancy if it meets its goal of increasing that by 5 years by 2035.
