What’s the Key to a towering Life?
Fortunately, the scientists have a simple take away note: diet and exercise are the key.
Ah… There’s a statement of scientific fact that makes sense. All that prattle about insulin receptors, genetically engineered mice, and other such nonsense only serves to confuse the issue. Let’s have some straight talk, with a bit of practicality thrown in for good measure.
Yes, diet and exercise. Eating less, and exercising more, manufacture the body’s peripheral tissues more sensitive to insulin. The conclusion is lower insulin production, resulting in less insulin circulating in the brain, resulting in a longer life.
But, lest we fall into the prattle trap once again, let’s review the central notice:
Diet and exercise are the keys to a towering life.
To read more about the study, see that from Reuters. To read more about healthy diets and exercise, see that from the HealthCentral Network.
CouldIt’s not precisely Science 101, but researchers at Children’s Hospital in Boston have a thought or two to share on longevity.
It works like that:
The amount of insulin in the brain may be the key to living longer. They engineered mice with defective genes to imitate various capabilities of insulin management. The gene they targeted is known as insulin receptor substrate 2 (Irs2). One group had no copies of the Irs2 gene, resulting in diabetes. The second group had a restricted copy of the gene, resulting in distinct advantages that extended their lives.
The second group lived slovenly lives, overeating and packing on the pounds - attributes that should shorten life. But, considering the mice had been designed to use less insulin in the brain, they actually lived longer than normal lab mice. In fact, they lived an average of 18% longer.
