What is the best source of information on the subject of slowing down or even reversing the aging process?

Question

I'm 45 years old and I feel as good as I did when I was 22-in more ways than one. I feel physically fit and pyschologically as enthusiastic as ever. I have been getting moderate amounts of exercise-some vigorous and some not so vigorous-and I have been very careful about my diet for a number of years now. I feel like I have found the fountain of youth; I'm just not sure where I found it. In other words, I'm not sure which parts of my fitness regimen are the most effective: diet, supplements or exercise. I just feel that the more I know about aging, the more I can refine this fitness program of mine.
