65% of Cancers are Simply Due to Bad Luck
According to the American cancer Society:
“Cancer starts when cells in a part of the body start to grow out of control. Cancer cell growth is different from normal cell growth. Instead of dying, cancer cells continue to grow and form new, abnormal cells. Cancer cells can also invade (grow into) other tissues, something that normal cells can’t do. Growing out of control and invading other tissues are what makes a cell a cancer cell.”
Researchers have recently proven that plain old “biological” bad luck is a major contributor to getting cancer. Two-thirds of cancer victims of various types had neither risky habits such as smoking and drinking nor was heredity to blame. The researchers found that random mutations in the genes were the cause of up to 65% of cancers out there.
Out of thirty-one cancer types researched, twenty-two were found to be largely explained by these random mutations. The twenty-two cancer types included leukaemia and pancreatic, bone, testicular, ovarian and brain cancer.
Dr. Bert Vogelstein of the Johns Hopkins University School of Medicine in Baltimore compares it to losing the lottery:
“When someone gets cancer, immediately people want to know why,” “They like to believe there’s a reason. And the real reason in many cases is not because you didn’t behave well or were exposed to some bad environmental influence, it’s just because that person was unlucky. It’s losing the lottery.”
You Exhale the Fat You Burn
Many of us are obsessed with diets and fitness trends. Whether we are trying to lose weight or get stronger, it always includes losing that extra unwanted fat.
Have you ever asked yourself where all that extra fat goes? Many health professionals cannot answer this question correctly. The most common misconception among doctors, dieticians and personal trainers is that the fat that we lose gets converted into energy or heat.
According to a new study conducted by the University of New South Wales, when you lose weight, the mass of burnt fat is breathed out as carbon dioxide and goes into the air.
Professor Andrew Brown, head of the UNSW School of Biotechnology and Biomolecular Sciences explains:
“There is surprising ignorance and confusion about the metabolic process of weight loss.”
The study shows that in order to lose ten kilograms of fat you will need to inhale twenty-nine kilograms of oxygen. This will cause the metabolic process to produce twenty-eight kilograms of carbon dioxide and eleven kilograms of water.
Ruben Meerman, a physicist and science TV presenter explains:
“With a worldwide obesity crisis occurring, we should all know the answer to the simple question of where the fat goes. The fact that almost nobody could answer it took me by surprise, but it was only when I showed Andrew my calculations that we both realised how poorly this topic is being taught.”
Professor Andrew Brown and Ruben Meerman are hoping that their findings will be included in secondary school curricula and university biochemistry courses in order to correct the misconceptions about weight-loss.
You Can Think Your Way to Strength
The American Physiological Society (APS) recently published a study that shades light on the power of regular mental imagery exercise. During four weeks of immobilization, regular mental imagery exercises helped test subjects preserve some of their strength.
The study explains that strength is controlled by a number of factors. The most studied of these factors is the skeletal muscle. The role of the nervous system when it comes to its contribution towards strength is not yet fully understood. This research studied the role of the brain’s cortex in strength development.
The researchers designed an experiment to measure changes in wrist flexor strength in three groups of normal individuals.
Twenty-nine healthy adults wore rigid casts that extended from just below the elbow past the fingers, immobilizing the hand and wrist, for four weeks. Fifteen individuals who did not wear casts served as the control group.
Half of the subjects with wrist-hand immobilization casts were told to perform regular imagery exercises. They were asked to imagine that they were intensely contracting their wrist for five seconds and then resting for five seconds. There were thirteen rounds per session and each round included four reps. The other half of the group with the wrist-hand immobilization casts were not instructed to do any imagery exercises.
At the end of the four weeks the results were as follows:
- Everyone who wore a cast had lost strength in comparison to those who didn’t.
- The group that performed mental imagery exercises preserved 50% more strength than the group that didn’t.
- It took lesser time for the nervous system to fully activate the muscles for the subjects in the group that performed imagery exercises compared to the group that didn’t.
The study which was published in the Journal of Neurophysiology concludes:
“These findings suggest neurological mechanisms, most likely at the cortical level, contribute significantly to disuse-induced weakness, and that regular activation of the cortical regions via imagery attenuates weakness and VA by maintaining normal levels of inhibition,” the research team wrote. “Thus our findings that imagery attenuated the loss of muscle strength provide proof-of-concept for it as a therapeutic intervention for muscle weakness and voluntary neural activation.”
