Even if you eat all the right foods, exercise regularly and don't smoke or drink, you may not be the picture of health. Your inherited family genetic make-up could forecast a different story, one that you might not be able to easily control. Factor in not being able to view what's actually taking place inside your body and we can ask the question, "who really can ever possess true health in the first place? and what does true health look like?". The body can withstand alot of abuse, but take it too far and eventually it screams "ouch". Do what you can now, focus on your health pre-emptively; it's an investment in yourself that will pay off in the long run.
