The Duke of Cambridge has been hearing the stories of firefighters and other frontline workers on a visit to Chudleigh in South Devon.
Prince William visited the Fire Fighters Charity's Centre at Harcombe House to mark Emergency Services Day.
The Centre provides treatment for emergency services staffs' mental and physical health.
John Couzins, a firefighter for 31 years, has reduced mobility and struggles to walk for long.
The antigravity treadmill at The Fire Fighters Charity's Harcombe House centre in Devon has allowed him to regain some fitness in his retirement, in body and mind.
I've probably achieved more in a week here than I have five months at home, trying to do physio. The staff, the tuition, the guidance, you just really can't fault it. You suddenly lose the use of one leg, especially when I'd been so active was quite a blow and I've found, coming down here, psychologically it helped as well.
We've had people arrive in a wheelchair and leave walking, and for someone like John, that treadmill has been a big boost for him. It's given him the confidence in himself and his body and what he can do.
Today's visit by the Duke of Cambridge was timed to coincide with Emergency Services Day.
The Fire Fighters Charity was also able to show off its £1.8 million revamp, with therapy rooms to support those suffering with poor mental health, a subject close to Prince William's heart.
He also met families who've had support here, and the centre has helped some who were involved in the Grenfell Tower fire.
The Duke of Cambridge was himself a search and rescue helicopter pilot.
