Educators replace "MS Office training course" with proper GCSE computer course. Are astounded when numbers drop.

Seems obvious we need to educate people both how to use computers, and how to fully understand them. Plenty of space for both types of course.

M&S says labelling avocados with lasers is more sustainable

From now on I'm going to refuse to eat any food that isn't somehow associated with lasers. I shall call this The Laser Diet. And my book will make a fortune.

Laser fruit and vegetables! Takes me back to my teenage years.

My Dad ran a big fundraising campaign in the 80s to buy a surgical laser for the local hospital. At a big party to celebrate reaching the target, he had the laser itself proudly on display, with a supply of apples to demonstrate on.

His first, enthusiastic demonstration involved whacking the power right up to maximum and gleefully blasting a surprisingly wide hole through an apple in a matter of seconds. Sensibly, he had considered some of the issues with doing this, and had carefully positioned a second apple behind the first to stop it setting fire to the table.

What he hadn't considered was how much alarm this demonstration of laser power would cause to potential and former patients who imagined it might do or have done the same to their insides. This was well before low-power lasers were ubiquitous, and the main pop-culture reference for lasers was Goldfinger slicing James Bond in half. ("No, Mr Bond, I expect you to die!")

After a bit of thought, my Dad changed the demonstration. He turned the power down and took to carefully writing people's names on the skin of the apple. For some reason this was much more popular.
