Time changes everything except something within us which is always surprised by change (Thomas Hardy.)
Do you ever think about how you are aging? Second by second, hour by hour, day by day, we grow older chronologically. But the signs of biological aging often take us by surprise.? Some aging changes we can recognise. It gets harder to read without glasses. Our hair starts to grey. Our joints feel stiff when we first get up.
But other changes are like the submerged part of an iceberg. Without specific testing, we don’t know that our immune systems are becoming less efficient, or our kidneys or liver don’t work so well or our bones are getting thinner.
So is aging inevitable and unchangeable? The Intrinsic or programmed senescence theories imply that aging is predetermined in our genetic blueprint like the programming that guides a single cell to grow into a baby. The extrinsic theories imply that aging results from cumulative damage from environmental exposures to pollutants, toxins or radiation, that occurs over our lifetime.
It seems likely that both forces apply. Genes involved in cell maintenance and repair and immune functions are of primary importance in the aging processes and expression of these genes may be sequentially turned on and off by pre-programming. But we also know that oxidative damage to these genes and cells plays an important role in aging and this is something we can possibly control.
An intriguing question – Do all our body parts and systems age at the same rate? Most people have one or two body systems that plague them more than others. For me it has been my musculo-skeletal system, muscles, bones and joints. For others it might be brain health or digestive system problems. Researchers are looking at genes and other biomarkers to differentiate aging of various functions in an individual. For example a person may have the heart function and blood pressure of a young individual, but an aged immune system.
There are ways in which we can intervene to delay aspects of aging though lifestyle choices. Changes in how and what we eat, our physical activity, even our thoughts can change gene expression. More about that later in the alphabet!
It certainly seems that is some cases we can turn back time. As for me, I keep wondering when my hair will turn grey to catch up with my increasing need for stronger reading glasses. What’s your Achilles’ heel of aging?
This year I have been really struggling with aging. I turn 50. Having had a hysterectomy in 2016, I am now on the cusp of menopause. It took a bit because I kept my ovaries. However, here I am and damn is it hard. No sleep, weight gain, depression. I had to put up with a period and my reward is menopause? Eek! I’m eager to read more about this in your writing.
Hi Jennifer. Been there done that – well not the hysterectomy bit. Now in my seventies, thanks to my GOLY roadmap and my health and anti-aging business I feel closer to 50 than my actual age. Happy to chat with you.
Interesting topic! I had a burnout a few years ago and after that I’ve learned to look at ‘energy’ in a different way and (hopefully) listen better to my body’s signals. It became clear how closely related body and soul are, that they mutually influence each other. I look forward to read more about this!

Thanks for the comment Gunilla. I will check out your blog. I have to say I too look at a lot of things differently since my road back from back surgery,
