The STAT magazine’s Sharon Begley reminds us how our body ages after our 20’s and after 30’s when our aging starts “afflicts different body parts to different degrees”. However, the aging process is highly individualized.
… just as people have an individual genotype, so too do they have an “ageotype,” a combination of molecular and other changes that are specific to one physiological system. These changes can be measured when the individual is healthy and relatively young, the researchers report, perhaps helping physicians to pinpoint the most important thing to target to extend healthy life.– A Standford Study published on Nature (source: Scientific American)
Dr Michael Snyder, a biologist who led the study, says:
Of course the whole body ages. But in a given individual, some systems age faster or slower than others. One person is a cardio-ager, another is a metabolic ager, another is an immune ager, as shown by changes over time in nearly 100 key molecules that play a role in those systems. There is quite a bit of difference in how individuals experience aging on a molecular level.
Yes, good news: We have real control over how our bodies age. Aging is happening on a cellular level at every moment, so for a long and healthy life, it’s vital to stay on top of the changes within your body and your mind.– Nicole Saporita on Good Housekeeping
In the article, she explains how our body changes in our 20’s, 30’s, .. 50’s and 60’s and how we can reverse the aging process by powering up our body with good healthy diet and exercises.
