This was a very extensive and detailed analysis. By following general guidelines about diet and exercise, men lived on average for 12 years longer and women 14. nothing fancy. No high intensity interval training or low-carb diet or meditation. Just a reminder that people can become paralyzed with too much questionable information about what is good or bad for them as a unique individual when following certain general guidelines should be much less stressful and clearly give you plenty of benefit. It remains unclear if the gains from a highly personalized approach to achieving optimal health and peak performance are substantial or just marginal. Most importantly, if they are marginal, is the return worth the investment? The jury is definitely still out.
