Fitness and health studies really bug me. People perceive them as actionable when they absolutely aren&#x27;t and should not be.<p>If your goal is general health in life you only need to do three things (well 4)..<p>1) exercise regularly 
2) eat a balanced diet 
3) sleep as much as you need.
4) drink water.<p>Don&#x27;t get hung up in the details.
