OK, you guys....

I'm going to be working on some freelance health/fitness articles for a magazine and a web column. I would like your input on what types of articles you find useful - "you," collectively, represent people interested in health/fitness - many of you are parents - you obviously are clever shoppers :-) - you are located all over the county. A perfect cross-section. Right now I am in the process of gathering ideas so it would help to know what types of articles people read. This is a new venture for me, so your brain powers are appreciated. I am thinking in terms of topics like quick ways to increase fitness, women over 40, bla bla. Thanks for your input!
