This book is a simple and humble gift, a present, a legacy of past life and love. It is a tale of many joys, laughs, and even laughter, as well as tears that sometimes came to be shed. It is a small present without any monetary or significant value of any commercial interest. Nevertheless, it is very exclusive because only the author can make this gift, because within the gift there are many experiences and anecdotes of a lifetime that only he is aware of. It is a gift that may one day be useful to dad or mom, when their son or daughter asks you to tell a story. Well, finally in decades to come, this dusty and forgotten old gift might have served for something useful. At the request of my great friend Mario Ignacio Zunzunegui, I allow myself to review his book where he captures his memoir with absolute reality. We first met many years ago through the sport of rock and high mountain climbing in Mexico City. I wish to testify that Mario recounts with absolute veracity events in his book and in which he cites me as an active participant. I congratulate Mario for his excellent memory in recounting those events in which he names my sister, Yoselinda, and me. We planned a trip to climb the rock El Zorro in the state of Hidalgo, in which Mario made the daring act of bringing her down from the summit by rappelling a hundred meters tied to his back. I feel God's blessings by Mario's return to his faith and Christianity after having such bad experiences which involved him with drugs and drug trafficking. I want to reiterate my deep friendship and admiration to my dear friend. Juan Cuellar
