Let me tell you that life as it is now, it was not before. When I studied my career, things were very different.Monterrey would not think that one of the most unsafe cities in the world. 27 years ago we had no phones, microwaves or talk, or I have no idea of the exact dates of when they were introduced this series of technological advances, but what if I'm sure is that to have Blar by phone outside the home, had to have some coins (Mexican peso course), or a prepaid phone card to reported.The first computer I had not had internet access and it was cassette, computer software were handled, but nothing to do with whom we have now. If you wanted a mobile phone, had to pay two thousand dollars to bring a suitcase in the car with a phone that God knows how it worked (ie I did not have one), although the weather was part of the possessions of wealthy people (class stocking up), the washed air was the best and economical way to cool off. There was no diet sodas, and when the first came out or when I learned that first came out I already had 18 years and was called TAB, still exists but not in Mexico. Diet foods were something like a hologram, or maybe we knew existed but could not have it available unless you bought in the U.S..
