“Regular Exercise May Keep Your Body 30 Years ‘Younger’…The muscles of older men and women who have exercised for decades are indistinguishable in many ways from those of healthy 25-year-olds, according to an uplifting new study of a group of active septuagenarians...These men and women also had much higher aerobic capacities than most people their age, the study showed, making them biologically about 30 years younger than their chronological ages, the study’s authors concluded… Worryingly, statistics and simple observation suggest that many elderly people experience frailty, illness and dependence… But science has not established whether and to what extent such physical decline is inevitable with age or if it is at least partially a byproduct of our modern lifestyles and perhaps amenable to change. There have been hints, though, that physical activity might alter how we age. Recent studies have found that older athletes have healthier muscles, brains, immune systems and hearts than people of the same age who are sedentary…for the new study, which was published in August in the Journal of Applied Physiology, researchers at Ball State University in Muncie, Ind., decided to look at a distinctive set of older men and women. ‘We were very interested in people who had started exercising during the running and exercise booms of the 1970s,’ says Scott Trappe, the director of the Human Performance Laboratory at Ball State and the new study’s senior author… the muscles of the older exercisers resembled those of the young people, with as many capillaries and enzymes as theirs, and far more than in the muscles of the sedentary elderly… The active elderly group did have lower aerobic capacities than the young people, but their capacities were about 40 percent higher than those of their inactive peers. In fact, when the researchers compared the active older people’s aerobic capacities to those of established data about “normal” capacities at different ages, they calculated that the aged, active group had the cardiovascular health of people 30 years younger than themselves…Together, these findings about muscular and cardiovascular health in active older people suggest that what we now consider to be normal physical deterioration with aging ‘may not be normal or inevitable,’ Dr. Trappe says…”

Caleb in the Bible proclaimed that he was as strong as he was in his 80s, and he was in his 40s. Modern research continues to affirm that this was not an idle boast! God promises in Psalms 103:5 that His food will renew youth. Old age and death are inevitable (unless the Lord comes beforehand). However, weakness in old age can be postponed to a high degree according to the Bible and modern research.
Imagine what living according to God's wisdom in regard to morals, diet, hard work, exercise, etc., will do for us!
