The King hailed one of Prince Harry's former Invictus Games colleagues as "remarkable" during a visit to the Imperial College London's Centre for Injury Studies on Wednesday.
The monarch, 76, viewed the centre's cutting-edge virtual reality biofeedback technology – demonstrated by former Army captain and parasport athlete David Henson – which enhances rehabilitation following limb loss.
As the pair shared a warm greeting, talk soon turned to the Invictus Games, which Prince Harry founded in 2014. Watch below...
"Are you still taking part in games and sports?" the King asked.
"So I'm a touch too old, I think," Mr Henson joked. "I did the Invictus Games in 2014 and 2016, Paralympics in 2016 and I stayed one of the trustees of the Invictus Games until the end of 2023 - so I've certainly been involved with it. I'm back in the defence industry now."
"Fantastic," Charles replied.

Harry has shared a long friendship with Mr Henson, who was even invited to the royal wedding in 2018.

Cameras captured the Duke's hilarious reaction as he pretended to take the snack away from the toddler before entertaining her with a series of funny faces.

As Mr Henson demonstrated his "robotic legs," explaining to Charles that one leg was amputated above the knee, and one through the knee - so it took a while to get the prosthetics to the correct position.
The King then enquired after his wife and three children, and told him: "You are a great example to us all."

When Charles held a video call with Dr Hnat Herych, chief of general surgery at Unbroken, he told the monarch: "Your Majesty, on behalf of my colleagues and my country I wish to express by deepest gratitude for the United Kingdom’s unwavering support for Ukraine, in these turbulent times.
"Britain has not only remained our steadfast ally but has also demonstrated true global leadership in defending Ukraine and standing up for freedom.
"The commitment of Your Majesty and the British people has been invaluable to us and we…hope for Europe's support in these critical times."
