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.’

                        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.

Disparity in life spans of the rich and the poor is growing

Sabrina Tavernise

February 12, 2016

      Experts have long known that rich people generally live longer than poor people. But a growing body of data shows a more disturbing pattern: Despite big advances in medicine, technology and education, the longevity gap between high-income and low-income Americans has been widening sharply.

      The poor are losing ground not only in income, but also in years of life, the most basic measure of well-being. In the early 1970s, a 60-year-old man in the top half of the earnings ladder could expect to live 1.2 years longer than a man of the same age in the bottom half, according to an analysis by the Social Security Administration. Fast-forward to 2001, and he could expect to live 5.8 years longer than his poorer counterpart.

      New research released this month contains even more jarring numbers. Looking at the extreme ends of the income spectrum, economists at the Brookings Institution found that for men born in 1920, there was a six-year difference in life expectancy between the top 10 percent of earners and the bottom 10 percent. For men born in 1950, that difference had more than doubled, to 14 years. For women, the gap grew to 13 years, from 4.7 years. “There has been this huge spreading out,” said Gary Burtless, one of the authors of the study.

      The growing chasm is alarming policy makers, and has surfaced in the presidential campaign. During a Democratic debate, Senator Bernie Sanders and Hillary Clinton expressed concern over shortening life spans for some Americans. “This may be the next frontier of the inequality discussion,” said Peter Orszag, a former Obama administration official now at Citigroup, who was among the first to highlight the pattern. The causes are still being investigated, but public health researchers say that deep declines in smoking among the affluent and educated may partly explain the difference.

      Overall, according to the Brookings study, life expectancy for the bottom 10 percent of wage earners improved by just 3 percent for men born in 1950 compared with those born in 1920. For the top 10 percent, though, it jumped by about 28 percent. (The researchers used a common measure – life expectancy at age 50 – and included data from 1984 to 2012.)
