The Long Downfall It was a sunny summer morning. We got in a very old bus and then drove off. The bus couldn’t accommodate all people, so two instructors sat in a raft which was towed behind our bus. We were heading to a wild place near the river. It was a rough mountain road with stones and sharp turns. When the bus was loudly bumping along on the stone, I was really worryed about two guys in the raft because they could fly out. Finally we arrived at the river bay with its sandy beach. The two guys from the raft were alright, moreover they were cheerful. After a few minutes everything was ready for rafting. I sat in front of the raft and took the paddle then we started our river adventure. It was exciting and full of fun. We passed through different rapids and whirlpools. In the middle of our journey we came up to a high cliff. Instructor told us: "This cliff is about fifteen meters high. And either of you could jump off it." I thought that I should definitely do it, because, probably, I would never have another chance. When I was climbing up my sense of fright was increasing too. I had to jump fast before I could refuse this idea. One guy jumped in front of me. I saw that he was fine and this fact gave me confidence. The one step into emptiness, then a free fall. It was the longest fall of my life. During this time I could have eaten a bucket of popcorn. Then I dived into the cold water. Life jacket straps squeezed my legs. Because it was dark there, I didn't know the right direction to the surface and therefore didn't swim. So, after about a quarter of a minute, my life jacket pulled me up. I saw a bright blue sky and rocks. It was wonderful to see it again. The stream of water began to carry me away and I started to swim intensively towards the raft.

Be careful with hyperventilation. It's an old and known recommendation for snorkeling. If you make some deep breaths before you dive, you will be able to swim under the water much more time. The cause is that our brain feels a need to breathe when the level of carbon dioxide is too high, and hyperventilation before a dive helps us to reduce it. But the problem is that a series of deep breaths barely increases the concentration of oxygen in the blood. This situation is very dangerous because oxygen can end before you want to make a breath. You will feel good under the water until the end, but then you can lose consciousness suddenly. I know some occasions, when strong swimmers were sinking so fast that nobody had time to rescue them. Be careful, if you want to use hyperventilation be sure that somebody is looking after you and might help you at any second.
