Aging presents challenges for programmers such as eyesight issues, pain, and mental concerns like lack of motivation and cynicism. Solutions include adjusting workspaces, changing fonts, using appropriate glasses, and adopting healthy habits like regular exercise and good sleep. Control over one's career and health can lead to a more satisfying and productive programming life as one ages.

What Developers Can Do to Continue to Program as They Age

There is no mental age limit for programming. Physically you start to have limitations, but in programming, if you reach that age and you are still programming, that means you are at the top of the food chain because nobody else has survived that long.
The biggest problem is the commute itself. Especially in the winter it causes physical stress. But homework, no limit.
Continuing to program and not becoming some manager keeps you mentally young. You are forced to work with younger people, you are forced to adapt to the lifestyle of young people.
Also, don’t forget that as time goes on, you’ll find older people in the workforce. There is an aging problem, Big Tech is running out of young people because not enough of them are being born. And a lot of those young people probably avoided a career in Big Tech because of the signals they sent with mass layoffs.
Over time, your physical limitations become less of a problem relative to other developers.

Something else you must realize as an older developer that still program. Your brain is trained to process very complex code from “before” SCRUM where everything is thumbed down to levels where everyone can code.
It is very important to keep that knowledge trained as long as you can because the way the modern software industry is heading, that trained knowledge will become very important to train younger people.
This knowledge is the lifeline of companies that want to bring back their products to become useful again.

Maybe continue programming… 🤷

I think if you compare Software Engineering to basically any other profession outside of maybe accounting or potentially some areas of Engineering, this is basically the best possible profession to work into your 70’s and beyond.
I get the feeling as the internet age folks get to retirement we will begin to see that they live longer due to the strong mental faculties developed during the time spent.
You get two strong things with software, strong hands and strong minds. Everything else withers away. If you do some basic strength training as you age you will be ripe to go into the late 90’s I think pretty easily assuming you stay safe and avoid any environmental related concerns.

I’d love to see more data on these topics. A lot of it is common sense and this article takes only a cursory glance.
