My doctor said Martin don't do this, don't do this, don't do this, don't swim, you're gonna die. I'm different because I found a way I don't feel any pain anymore. My name is Martin Strahl, 62 years old, born in Slovenia and I am professional Mara Tonsmimmer. I have five Guinness World Records by Swim the longest rivers on the planet. I have Swim, the Danube, Mississippi, Parana, Youngtze and Amazon. Everybody said man you are just nuts, you are crazy, the river will take you. He was having infections, his stomach, lower infection in his brain, hallucination, he was peeling off the skin. I thought this is the over for him, no one can survive this. Most people understand running a marathon. When you put this to the lab that Martin sets out to do, he says I'm going to swim now for 60 days, that's 60 of these marathons. Some people ask me how he can swim for so long, I don't know how, but you don't know how. Water killed people, usually. But not me, not me. I am like half animal, half human. Martin is most known for being an overweight athlete. I am a little, off a little sick, a little crazy. His whole life was nothing defined by normal. And just doing something that most people cannot even comprehend the thought of being able to do. So Michael Felves, what's different between me? Michael Felves is not Marathonson. He is much faster than I am, sure. He is very successful in the swimming pools. I'm successful in swimming the rivers. He is not ready, sure, for the Amazon because he is still skinny. When I swim, I'm losing 6, 700 calories per hour. My body is like a Mercedes BMW, good. Martin does not resemble an elite runner or a elite cyclist in their lean factor. So for Martin to be able to swim at that kind of range is really extraordinary. With Martin, I really am just baffled. When my body is in trouble, I swim. I have excellent memories on my life, this child at this beginning. But father was too much violent many times. And because fighting with me came home very smart. He was here always trying to catch me. Where to go? I jumped into water. He was running around. He said, come back. No, no, no, no, I was under the water. Sometimes more than two minutes, water became like part of my life, very good friend for my safety. I wasn't so confident at the beginning, very, very afraid. I didn't sleep. My pulse was very high even on the Amazon. To learn in the Amazon, most people would have just difficult to stay afloat. There's no way anyone could survive to walk in this river. On the Amazon was terrible moment attacked by piranhas. In your back, you feel fire, the heat so fast they opened my back. And I called fire my back piranhas. It is still the longest swim in the history. He had a lot of issues. The Mississippi River. He dropped 55 pounds in two months. He was just losing so much weight. So we even worry that he must be getting sick or something. I swam one of the most polluted today on the planet. I was just pollutioning everything. I was touching by lightning. I was unconscious one minute. Pushed melt with the water. I was slanting like a plan. We literally thought he was a dead man. There's guys called Martin died. I stopped for a couple of minutes and then go martin. Nothing happened. You know we're like I guess he's alive. He's fearless. He's not afraid of death. He's one of the people. I'm either going to do it or die trying. Most of the people simply don't understand how you can swim like 12 or more hours per day. When I swim, it's impossible to think about the stroke under the water. I even count this one, two, three, four, five, hundred. Then at the beginning that was terrible. It was lots of pain swimming hours and hours and the ocean slakes rivers. Many times I said by myself it's simply too hard. You have tears in your eyes. You don't know how to move this. What to do? But you have to swim. You have to finish this. It was hard to swim. And then on the den you...it happened. I found a way. It's hard for me to explain what is meditation or hypnotization. Here is something that helps me a lot. It happened what I was swimming. My concentration is very very deep like meditation. Then when it's done I don't feel any pain anymore. Can somebody explain it to me? Some physician scientist could say this is not possible. For him it's not possible but it's possible for me. I think that everything is here in your brain here. I am still strong. I can swim more. I would like to swim Grand Canyon. And another target is swimming around the planet. Because today water is not good. We are not on the right way. I went for peace, friendship and clean water especially. I am just a simple man. And I can change still this world. Thank you.
