I haven't applied this concept to my hiking diet, yet, but I try to apply it as much as I can to my daily diet. It is a good goal to shoot for, but I am not much for 100% purity on these matters - that's why I'm not a real vegetarian, even though I am about 95% of the way there.

Come to think of it, I use the 95% rule in many aspects of my life. F'rinstance, I have always found that, if I can meet 95% of the stated objectives of my job (as formulated by my employer) and the 95% I do includes all the most important stuff, my boss is usually delighted with my work performance. And if my house is 95% clean, I'm pretty happy with that.

Now, if I could just get back 95% of my hair, that would be perfect!
