If a bus hits you tomorrow, it could be argued there's not a lot a carrot juice could have done to prevent it. Or could it? Undoubtedly, there are many cases where, in isolation, diet would probably make no difference to the events that have shaped a life. But equally, we all know people who seem constantly dogged by ill health, and so often it seems to parallel their lifestyles that, in some respects, are out of control.
The fact is, if you're healthy and fit, you're probably a strong character who has the discipline to be in control. People will call you lucky (and you are). However you largely determine what happens in your life. If you eat just about anything that wanders into range and don't exercise, chances are you're losing control and "life" will largely determine what happens to you. But if you decide to take control of your life now and make the commitment to a healthy diet and active lifestyle you will reap the rewards of good health and you can become that "lucky" person.
Take control now and find out how healthy your diet is.
