Nathalie, the swimmer who lost a leg

Nathalie du Toit, the South African swimmer, was only seventeen when she lost her leg in a road accident. She was going to a training session at the swimming pool on her motorbike when a car hit her. Her leg had to be amputated at the knee. At the time she was one of South Africa’s most promising young swimmers. Everybody thought that she would never be able to swim competitively again.

But Nathalie was determined to carry on. She went back into the pool only three months after the accident. And just one year later, at the Commonwalth Games in Manchester, she swam 800 meters in 9 minutes 11:38 seconds and qualified for the final – but not for disabled swimmers, for able-bodied ones! Althought she didn’t win a medal, she still made history.

‘I remember how thrilled I was the first time that I swam after recovering from the operation – it felt like my leg was there. It still does,’ says Nathalie. The water is the gift that gives me back my leg. I’m still the same person I was before the accident. I believe everything happens in life for a reason. You cant go back and change anything. Swimming was my life and still is. My dream is to swim faster than I did before the accident.’

         CAN TECH DELIVER A SUSTAINABLE FUTURE FOR PLANET EARTH?

Sustainability means many things to many people, but it boils down to this: saving Planet Earth.

      Mankind1 , as a species, has been too successful for its own good – the global population is estimate to top nine billion by 2050, according to the United Nations Department of Economic and Social Affairs.

      As a result, there is already a strain2 on the planet’s essential natural resources, particularly food and water, which population growth can only aggravate.

      Meanwhile, our demand for energy has directed to the plundering3 of the earth’s hydrocarbons oil, gas and coal, producing a catastrophic climate change. In a month-long series of features on the theme of sustainability, Technology of Business will be examining the main challenges facing businesses and asking whether technology – which got us into this mess in the first place – can help get us out.

      Global megatrends are affecting the business environment

      Most companies are already being affected by climate change today, directly or indirectly, says *CDP, a global not-for-profit organization specializing in measuring business environmental impact.

       Extreme weather, drought and flooding can disrupt production capacity and affect supply chains for a whole range of businesses. For example, in a CDP survey of 70 European companies, 83% said they had operations in “water-stressed” regions, while 73% said water shortages posed risks to their own operations or those of their suppliers.

      Considering an increasingly globalised economy, few businesses can isolate themselves from the impacts of climate change, population growth and resource reduction, says Emma Price-Thomas, head of sustainability strategy at charity Business in the Community.

      “The world is changing very fast. Global megatrends are markedly affecting the business environment. If companies don’t address these and think longer-term, they may end up putting themselves out of business,” she argues.

      A lot of technology and research is being directed towards reducing water usage an industrial processes and designing products that need less water to work, she says.

                        When does the brain work best?

                     The peak times and ages for learning

      What’s your ideal time of the day for brain performance? Surprisingly, the answer to this isn’t as simple as being a morning or a night person. New research has shown that certain times of the day are best for completing specific tasks, and listening to your body’s natural clock may help you to accomplish more in 24 hours.

      Science suggests that the best time for our natural peak productivity is late morning. Our body temperatures start to rise just before we wake up in the morning and continue to increase through midday, Steve Kay, a professor of molecular and computational biology at the University of Southern California told The Wall Street Journal. This gradual increase in body temperature means that our working memory, alertness, and concentration also gradually improve, peaking at about mid morning. Our alertness tends to dip after this point, but one study suggested that midday fatigue may actually boost our creative abilities. For a 2011 study, 428 students were asked to solve a series of two types of problems, requiring either analytical or novel thinking. Results showed that their performance on the second type was best at non-peak times of day when they were tired.

      As for the age where our brains are at peak condition, science has long held that fluid intelligence, or the ability to think quickly and recall information, peaks at around age 20. However, a 2015 study revealed that peak brain age is far more complicated than previously believed and concluded that there are about 30 subsets of intelligence, all of which peak at different ages for different people. For example, the study found that raw speed in processing information appears to peak around age 18 or 19, then immediately starts to decline, but short-term memory continues to improve until around age 25, and then begins to drop around age 35, Medical Xpress reported. The ability to evaluate other people’s emotional states peaked much later, in the 40s or 50s. In addition, the study suggested that out our vocabulary may peak as late as our 60s’s or 70’s.

      Still, while working according to your body’s natural clock may sound helpful, it’s important to remember that these times may differ from person to person. On average, people can be divided into two distinct groups: morning people tend to wake up and go to sleep earlier and to be most productive early in the day. Evening people tend to wake up later, start more slowly and peak in the evening. If being a morning or evening person has been working for you the majority of your life, it may be best to not fix what’s not broken.
