As the Olympics Approaches, a Lesson in Overcoming Adversity

Bert R. Mandelbaum, MD

July 20, 2016

      I've known a lot of athletes who qualified for the Olympic Games ,______injuries. But I know of only one who qualified because of an injury.

      Cliff Meidl’s story captures the spirit of the Olympics.

      In November 1986, Cliff, a 20-year-old plumber's apprentice, hit three buried high-voltage electrical cables with a jackhammer. An estimated 30,000 volts surged through his body, exploding bone and cartilage from the inside ail the way up to his head. To put that into perspective, electric chairs use only 1500-2000 volts for executions. So it's safe to say that Cliff should have died.

      And he nearly did. His heart stopped. Paramedics were able to get it going again, but they had to resuscitate him on the way to the hospital.

      As part of a team with renowned plastic surgeon Malcolm Lesavoy, MD, and others, I got to work reconstructing Cliffs legs. Our best hope was to avoid amputation.

      But very quickly, we noticed something else going on - something that had nothing to do with our expertise. Through every step of his painful rehabilitation, Cliff grew more and more determined. He never complained. He just asked, "What's next?"

      Before he had even finished the rehabilitation, Cliff started paddling various watercrafts. The days spent on crutches had already strengthened his upper body, and he took naturally to the sport. The same year in which he was injured, he began competing in canoe and kayak events, and in 1996 he qualified for the Olympics - not the Paralympic Games, the Olympic Games.

      Four years later, in Sydney, Australia, I was overseeing the sports medicine team at the Olympic soccer tournament. I was sitting in the stands during the opening ceremonies when Cliff walked into the Olympic Stadium carrying the Stars and Stripes.

      It's a long-standing tradition for delegations of athletes to select one among their number to bear the flag, and the choice often symbolizes some extraordinary accomplishment. I had no idea that Cliff would be selected. So when he strode into the stadium with a normal gait, I nearly broke down.

      Moments like that reinforce what I have always believed: that sport can bring out the best in us all.

      The Olympic Games (...) are devoted to celebrating the human capacity to improve body, mind, and soul.

      They are about taking part - not necessarily about winning. Cliffs peers in the US delegation of 2000 recognized that when they elected him to bear the nation's colors. He never won a medal at the games, but the spirit with which he overcame adversity inspired all of them.

      The Olympic motto - faster, higher, stronger - can help our patients realize that the real victory is the "win within." The Win Within: Capturing Your Victorious Spirit is the name of the book I wrote to show people that coming back from adversity is part of our heritage - that we as human beings are more adapted to adversity than we are to success.

      Adversity is the engine of unimagined opportunity. It can unleash our energy and stimulate our will. It moves us to succeed. If I don’t have food, I have to go get some. If I’m cold, I have to build a shelter.

      I remind patients who don't participate in sports that they have the heritage of athletes. We all have the genes of pursuit-hunters who survived by running down their prey and running away from their predators. That's why even now, in 2016, when we go out and take a run, we feel good. We get an endorphin surge and our lipids go down. Our hearts and brains become clear.

      The life of sport and sport of life are interlinked. Exercise is our birthright; it's our legacy; it's why we are here.

      We no longer have to fear saber-toothed tigers or cave bears. But when you look today at how people can be successful in 2016, it's by avoiding the predators in our urban life: overeating, inactivity, and smoking. And it's by rising to meet adversity.

                           How things work: 100 scientific explanations

      Preservation property has always been important to humans. Historians in the ninth century were the first to record the use of varnish, a protective liquid composed of resins, natural oils, and alcohol, among other ingredients. Furniture makers learned that if they painted coats of the stuff on a piece of furniture or wood floor, it made it impervious to liquids and their damage and shielded it from normal wear and tear. And the makers liked the shine furniture had after it was varnished.

      Varnish comes in many formulations. Some are oil based, using linseed or tung oil, while others are water-based. Varnish cures, or dries, on what it’s painted, creating a glossy, clear film on the surface. Some oil-based varnishes can turn to a yellowish color; water-based varieties do not. Wood must be carefully cleaned and sanded before any varnish is applied. Several coats are often required. All varnishes contain resins — terpenes with five-carbon molecules called isoprenes and also include a drying oil or solvent to reduce drying time.

     Although furniture and flooors are still the most frequently varnished items, the wooden hulls of boats are also often varnished. Clear nail polish, a type of varnish, can be used for countless small fixes: dab small amounts to keep splintered wood from snagging, prevent ink from running, and stop buttons on clothing or screws on sunglasses from coming loose.

Bento boxes

    People in offices in Japan often have a bento at lunchtime. They do not eat a meal in a restaurant; they eat a bento in the office. They regularly have a menu for the bentos in the office and they telephone a bento store with their orders. The people at bento store make the bentos and take them to all the offices at about 12p.m.

                  LANDFILLS AND THE INTRODUCTION OF NANOMATERIALS IN WASTE

      Waste disposal on land (dumping) and landfilling remain the most prominent waste management techniques used ______. The standards and practices for this type of waste disposal vary greatly ranging from uncontrolled sites to highly specialised and controlled engineered landfills. The potential ______ of contaminants through landfill gas and leachate is largely dependent on landfill design, site conditions and the sophistication of the control measures in place, ______ landfill gas recovery and leachate collection and treatment systems.

Modern engineered landfills use ______ barriers, with few relying on natural barriers, to line the bottom of a landfill and incorporate collection systems for both leachate and landfill gas. The purpose of these collection systems is to capture and treat leachate and landfill gas; ______ preventing the migration of leachate into ground/surface water and the release of untreated landfill gases to the atmosphere. An un-engineered landfill would be considered an uncontrolled system due to the lack of environmental controls, potentially resulting in significant environmental exposure of contaminants.

      Because of widespread use of ENMs in a broad range of products, it is possible that some ENMs ______ through landfill gases; however this report will primarily focus on ENMs that may be present in landfill leachate, as this is considered to be the primary means by which ENMs could be transported______ a landfill. Characterisation of landfill gases to identify the presence of ENMs ______ an important area for further research.

      Landfill leachate is generated when rain passes through the waste mass and by the liquid generated due to the breakdown of waste ______ the landfill. The composition of leachate is extremely ______ depending on the type of waste landfilled, the quantity of precipitation, the construction and operation of the landfill, the age of the landfill and other factors such as pH, temperature and microbial populations.

                               Would it be wrong to eradicate mosquitoes?

      The mosquito is the most dangerous animal in the world, carrying diseases that kill one million people a year. Now the Zika virus, which is carried by mosquitoes, has been linked with thousands of babies born with brain defects in South America. There are 3,500 known species of mosquitoes, but only the females from just 6% of species draw blood from humans - to help them develop their eggs. Of these, just half carry parasites that cause human diseases.

      More than a million people, mostly from poorer nations, die each year from mosquito-borne diseases, including Malaria, Dengue Fever and Yellow Fever. Some mosquitoes also carry the Zika virus, which was first thought to cause only mild fever and rashes. However, scientists are now worried that it can damage babies in the womb. There’s a constant effort to educate people to use nets and other tactics to avoid being bitten. But would it just be simpler to make an entire species of disease-carrying mosquito extinct?

      In Britain, scientists at Oxford University and the biotech firm Oxitec have genetically modified (GM) the males of Aedes aegypti - a mosquito species that carries both the Zika and Dengue viruses. These GM males carry a gene that stops their offspring from developing properly. This second generation of mosquitoes then die before they can reproduce and become carriers of disease themselves.

      So are there any downsides to removing mosquitoes? Mosquitoes, which mostly feed on plant nectar, are important pollinators. They are also a food source for birds and bats while their young - as larvae - are consumed by fish and frogs. This could have an effect further ahead in the food chain. Mosquitoes also have limited the destructive impact of humanity on nature. Mosquitoes make tropical rainforests, for humans, virtually uninhabitable. Rainforests are home to a large share of our total plant and animal species, and nothing has done more to delay man-made destruction over the past 10,000 years than the mosquito.
