“On your watch, you’re not going to measure your ECG continuously because you drain your battery straight away.”In addition, movement – both of the wearable itself on a wrist, for example, and general movement of the person wearing it - can “create noise” in the data it collects, he adds, making it less reliable.

Dr Wei points to the ring on my finger.“The gold standard to measure the heart rate is from the wrist or direct from the heart,” he says. “If you measure from the finger, you’re sacrificing accuracy."It is the role of software to fill in such data gaps, he says - but there’s no international standard for wearables here - for either the sensors and software that power wearable devices, or for the data itself, and even what format it is gathered in.

The more consistently a device is worn, the more accurate its data is likely to be. But here’s a cautionary tale.Ben Wood was out for the day when his wife received a series of alarming notifications from his Apple Watch, telling her he had been in a car crash. It advised her to text him rather than call because he may need to keep the line clear for the emergency services.

The alerts were genuine, and sent to her as his emergency contact – but in this case unnecessary. Ben was out at a race track driving some fast cars. He admitted that he “wasn’t very gifted” at it – but said he felt safe at all times.

“The boundaries between incident and alert need to be managed carefully,” he wrote in a blog post. “I’m curious to see how device-makers, emergency services, first responders and individuals think about this technology in the future.”Part of the message reads: "The German War is now over.

"At Rheims last night the instrument of surrender was signed which in effect is a surrender of all personnel of the German forces all equipment and shipping and all machinery in Germany."Reflecting on the message 80 years later, Mr Morgan, said: "I was so pleased to get it because, like all of us, we all wanted to get back home... but you can't do it overnight."

He met the Princess of Wales on Monday as part of VE Day commemorations at Buckingham Palace.John James Woodman was born on 1 July 1919 in the Aston area of Birmingham.
