Getting fit?...but need some new friends to assist with eating and workout regime

As I get older it seems more difficult to keep fit. What should I eat? Not in general, but for today's meals. How much should I exercise. Hereagain, not in general but I ran 4 miles yesterday, and 9 for the week, what should I do today. And of course, I am not one to hire a team of professional cooks, trainers, etc.

So I searched here's a list of social network eating/workout sites that can assist anyone (senior or youngster) with helpful hints and encouragement.
