Do you know what is easy? Easy is something you can do. That's too easy … If you can do is easy, just learn how. Make sense? That means education. The first thing you learn to do one thing and that learning makes it easy for you to do. Then practice, practice, practice until good at doing what is easy is thing.That success. It is not difficult or complicated. You can not do anything out of it until that first occurs within yourself.You prepare for learning by creating a plan. That's where your goals are, are the plan for your life. (Yes, you should plan all the things you want to learn and do in your life. If you do not know where it goes you might as well sit on your ass like the beginning of a path. Either way you go in the spot) .. Let's talk about learning, because it is a lifetime process. This is something we start getting into school.As a student, I remember thinking (about things like history and civics, and even some math) there is no way I'd use these things in real life. What a surprise to me that I had, some of those thoughts came back to hurt me later.Luckily years finally learned how much he had some of these things in school. I give you a example.I enjoy diving, but only one tank of air in the tire on the back and down to 100 meters underwater. You get in trouble doing things like that.First must learn the basics of diving techniques, but also know some technical stuff too.When underwater observing and studying the beauty of coral and fish swimming around you, your nitrogen accumulates body. How much depends on how deep to go, and how long you stay at that depth. The deeper they are, the greater the pressure, the greater the pressure, the nitrogen accumulates. The time you stay at a given depth indicates the opportunity that nitrogen is more to build your body.If to maintain the nitrogen content of your body and keep it within reasonable limits there is no problem. When you return to the surface of nitrogen emissions from your body. The water pressure decreases around and let the nitrogen out.But if the building is not excessive nitrogen can form bubbles in the blood and when they surface. It's like what happens when you shake a can or bottle … bubbles and then try fast.Those bubbles in the blood out of this problem. We call it decompression sickness (or curves), and if non-emergency medical assistance, death.Decompression probably suffer pain and illness is serious, but easily avoided if you know how to handle. Just be sure not to stay long enough for the determination of nitrogen high.So know how to build the content of nitrogen in your body is too high and it is time to swim to the surface of the water? Well, this is where school comes in to find out how long you can stay at a given depth before your body absorbs more nitrogen than is healthy for you. We know what kind of training go diving, but the basic capacity to do was choose school.It is a mathematical thing. To calculate how much nitrogen can be constructed for each minute you stay at any depth count. Then you know how long you can dive before returning to the ship or shore.More three minutes at 100 meters and risk curves, and can dive safely for a hours at 25 meters. But you can not dive for one hours at 25 meters and 100 meters to go. It would hurt you.So pay attention to all teachers to meet in life. You may need the information.
