This was a gift for my hustband and he just loved it. I gave it a few moths before his marathon. He sayed thanks but did not look that into it. But when he started reading it he became very exited and keept thanking me. He said that the weid part is that your in a way know most of the thing in the book but it is not until it is put in contains it really make sense. He started earting and drinking as desriebed in the book and it was a success.
