but if I had to stress one point, one thing you can do to improve overall performance, it’s this: control your sugar intake, and learn to understand how much sugar is contained in what you eat and drink. This isn’t just about cutting calories, although I do want you to control your weight. This is about how your sugar intake affects your performance. I want your energy and blood sugar levels to be steady, without the peaks and valleys, so you can function at a peak level for a longer time. Get rid of the highs and lows, the crashes, the sudden fatigue, so you’re not chasing them with more sugar.
Jump Attack
Tim S. Grover
Although caught off balance by Torch, the Germans had moved swiftly and effectively. Before the unblooded American troops could advance, Axis troops had occupied Tunisia and fortified it with men and arms from Sicily. While the GIs trudged through the winter rains and the mud, Stuka dive bombers and Krupp 88 artillery pieces pounded them, their tanks, and the Allied air cover. Then, in February 1943, counterattacking Germans hurled the Americans back through Kasserine Pass. At the time, the pass seemed an Allied disaster. It turned out to be disastrous for the Axis. Patton replaced the corps commander there, recaptured the pass, and teamed up with Montgomery, who had arrived after chasing Rommel’s Afrika Korps all the way from El Alamein. The Germans in Africa were doomed; Rommel flew off to tell Mussolini and Hitler that his men must be evacuated. To survive, the Korps needed at least 140,000 tons of supplies every month, and the Allied navies’ command of the Mediterranean was reducing the German trickle from 29,000 to 23,000 to 2,000 tons. Mussolini and Hitler told Rommel he was a Cassandra. Look at Kasserine Pass, they said triumphantly; that was what happened when Aryan troops met mongrelized Americans. To Rommel’s horror, they were shipping men into the beachhead. Thus, when the Allies snapped their trap shut in early May, they bagged nearly a quarter-million POWs. This, combined with battlefield losses, meant the Axis had lost 349,206 in French Africa. The Americans, in their first campaign, had sustained just 18,500 casualties.
The Glory and the Dream
William Manchester
A clever follow-up study by an international team of scientists recruited a group of young women, all with normal visual acuity but some who had poor depth perception and others with good depth perception. Each woman had a catching pretest—in which she had to snag tennis balls shot out of a machine—followed by more than 1,400 practice catches over two weeks, and then a posttest. The women with good depth perception improved rapidly during the training, while the women with poor depth perception didn’t improve at all. Better hardware sped the download of sport-specific software.
