““[Lemaire] has been working on the thirteenth-root challenge for a number of years. Previously, his best time had been a sluggish 77 seconds. Afterward, he told the press, "The first digit is very easy, the last digit is very easy, but the inside numbers are extremely difficult. I use an artificial intelligence system on my own brain instead of on a computer. I believe most people can do it,but I also have a high-speed mind. My brain works sometimes very, very fast.... I use a process to improve my skills to behave like a computer. It's like running a program in my head to control my brain." "Sometimes," he said, "when I do multiplication my brain works so fast that I need to take medication. I think somebody without a very fast brain can also do this kind of multiplication but this may be easier for me because my brain is faster." He practices math regularly. So that he can think faster, he exercises, doesn't drink caffeine or alcohol, and avoids foods that are high in sugar or fat. His experience of math is so intense that he also has to take regular time off to rest his brain. Otherwise, he thinks there is a danger that too much math could be bad for his health and his heart.””
