Last week, I achieved the eponymous age of The Beatles’ song, “When I’m Sixty-Four”, as featured on their “Sgt. Pepper’s Lonely Hearts Club Band” album. Like many of the people who commented on YouTube, I was just a kid when I heard this song on its release; and I, too, could not imagine being that age.

For one thing, at that time, back in the late 1960s, my grandparents, great uncles and great aunts were all in their mid- to late-sixties; to me they were already so old, even ancient. God forbid that I should end up like that! Of course, given their life experiences, perhaps it was not surprising that they seemed so wizened (physically and metaphorically) before their time. Living through two world wars and a deep economic depression takes its toll. Also, in 1967, life expectancy was around 72 years; now it’s close to 82. And back then, the UK state pension age was 65. Consequently, people seemed “old” because that’s how they were expected to behave, and they were treated as such by government and society alike.

Now I have reached this milestone myself, I realise more than ever before that aging is also a mental construct, not just a biological process. Hence the notion of “subjective age”. If you think you are too old to do something, then you are probably limiting your options (and narrowing your outlook). Little wonder that articles about “life begins at 60” seem popular!

I know have had a very different life experience to my grandparents. For example, two of them never went abroad, three of them never drove a car, and one didn’t live past the age of 50. Unlike them, I don’t have children or grand children, I have lived outside my country of birth for more than half my life, and I have traveled to far more countries than they ever did.

On the other hand, unlike many of my parents’ generation, many of whom enjoyed jobs with life-long career expectations, I have had a more erratic and inconsistent work experience – similar to my grandparents. In their cases, they either had to create their own work (e.g., small business owner) or endure periods of patchy employment. In my own case, I went into corporate employment at a relatively late age, and exited at age 50 – hitting something of a grey ceiling. Mainly for that reason, I have endeavoured to remain curious, stay open-minded, be flexible and willing to adapt – which I believe has helped me to maintain a “younger” subjective age. I think it also helps to have non-work pursuits and interests, so you can remain active if (and when) your employment comes to an end. Plus, having social interactions with people who are not all the same age as you can help to develop more of an inter-generational perspective.

One last comment – I was very surprised to read recently that according to a global study, boomers like me may be living longer, but not healthier, than our parents and grandparents. Despite medical advances, our lifestyles and other factors may result in more chronic disease and illness. I’m not suggesting that this decline is due to psychological ageing, but I can’t help thinking that if you say you are old, old age (and all its ailments) will soon catch up with you.
