The lovely person you met on Tinder and took for dinner? Your romance probably won't make it past the sorbet course.

But back in the day, some things were made to last forever - and here's proof.

A Polish mechanic from Gdansk has been discovered using a Commodore 64 computer to run his business for 25 years.

The picture was posted to a computer forum after watching the unnamed engineer balance driveshafts using the creaky old computer.

It then went viral, reportedly pushing up the second prices of the old computers on eBay in the country.

On Facebook, the woman who posted the picture wrote: "Yesterday I came across a drive shafts calibration service. You wouldn't believe what the owner uses to calculate the weight.

"It all has been working for the past 25 years despite the system being flooded through a leaking window in the past and most likely s*** on by birds. The software is home-made and it works, gentlemen, it works!"

There are still about 100 firms around the world making custom hardware for the C64, which is famously durable and easy to adapt to any task.

The Polish mechanic was able to fit all manner of complex sensors and other gadgets to help him change driveshafts.
