most people was using supplements for and excuse to not eat right
You've got that exactly right. I have always taken my vitamins etc. the old fashioned way. I have also, for most of my life, taken the time to get good sleep.
I don't get sick and for the most part feel pretty good. I felt my worst for the period of time where I was in a high stress job and probably not sleeping and eating as well as I could have. It was also the only period in my life where I had a cold that was anything more than sniffles for a few days.
Its funny how so many people ignore the simple (though not always easy) solution and look for the magic bullet.
