We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
This month’s Harvard magazine has an article on just this topic. Scroll down to the section titled, ‘Eating to Excess: Metabolic Inflammation’.
“The metabolic stress that is a hallmark of modern life, the stress that the body has not evolved to handle, is constant eating, he continues. When people eat, energy and nutrients enter the body rapidly, are processed, produce in turn a lot of by-products, and then need to be reduced to “functional substances that are distributed throughout the body, and then disappear very quickly. Many cells and tissues actually undergo a huge amount of stress during this process,” he explains, “as they store appropriate nutrients and dispose of harmful intermediates.” Part of this process also involves mounting an immune response. “The pancreas, for example, must secrete four to five hundred milliliters of enzymes every day” to be able to manage the incoming energy load with every meal. “If you place these organs under constant stress, they start malfunctioning.” The consequence is that “right now, one out of every 10 individuals has diabetes. One out of every four individuals has fatty liver disease. And if you reach a certain age, one out of every three individuals will develop neurodegenerative disease.”
The metabolic stress that underlies these conditions comes from the daily imbalance between how much energy people consume and how much they need, and can process in a healthy manner. The long-term consequence of overconsumption, combined with lack of sufficient expenditure, is stored energy—the accumulation of fat...”
Also interesting in that article is a bit about the benefit of muscle inflammation due to stressful exercise. Muscle damage, of course, is how we build strength.
I have a question about building muscle in your old age. I'm 68. When I was younger, if I did work that used a certain group of muscles, those muscles would strengthen. The work would get easier. Now, it seems like that doesn't happen. They just continue to hurt and do not seem to strengthen at all. Is this typical?
