Over the winter, i seem to gain alot of weight. As a high school quarterback, that is not acceptable. Last summer, i think i went from 160 to 150. That's my gross weight loss. I'm not even talking about how much fat i lost. I gained a good amount of muscle over the summer, so i probably lost over 15 lbs of fat. I got my six pack back, and life was great. After the season, i just quit, and now my six pack is back in the fridge. I'll probably order some up next week and start again. These are great, and the results are amazing.

This is not a new book;perhaps that's why it is so useful.There is no gobblygook, no arcane economic theories with fancy lables.What there are in this book are many examples of - - if the government takes this action to make this or that happen, the unintended consequences have proven to be and will probably be again something quite different, and usually not positive.Sound experiential economics in my view, clearly written; and a tremendous help to understanding what will probably happen if the nation takes on more debt, subsidizes this or that interest, taxes one interest at the expense of another, etc.I liked it; I could read and understand it.

I do like the book and use it alot for school. The part that I use most is the Directory of Words Cited. Unfortunately, many times the exact type of work to be cited is not listed. For instance, a book with an editor in multiple volumes in an edition other than the first is not covered. Neither is an article from a journal obtained from a database.
