How do you know that you are well? Last year (2009) over 172 billion dollars was spent on being healthy and looking good. People have started and stopped weight loss programs, diets, exercise programs......How does anybody know whether these things are working? Would you have been successful if you had stuck to it? Did you quit too soon? Or did you not quit soon enough?
There is just so much going on now that we are all concerned about our health, health care, diet, exercise, nutrition.
So have at it and let us have a lively debate.
