When you're faced with the challenge of farming 1600 acres of hills in North Wales, the last thing you need is a bad back.
Hedd Pugh knows all too well that back pain can strike when you least expect it.

"But the nature of farming means that life goes on and you have to get on with the job in hand," said Mr Pugh, who has been farming at Dinas Mawddwy in Gwynedd for more than 30 years.
"My advice is don't let back pain get you down. When it strikes you have to do your best to keep active and mobile. It is the only thing that works for me."
Mr Pugh's farm is stocked with 1200 sheep, so 'duvet days' are out of the question.
"I did develop some back trouble during my early 20s and it's the sort of thing that never goes away.
"But you have to look after yourself, take care when doing lifting work and manual labour. I find the best answer always is to keep busy and active."
Mr Pugh, who turned 50 in November, makes the occasional visit to a nearby osteopath, but usually relies on self-help to conquer any potential back problems.
"Pain is a very difficult thing to judge and compare in different people. We all have different pain thresholds.
"I have found there is little point in staying stuck in the chair and seizing up when back pain strikes. You have to work your way through it and get on with life.

"For example, there would be no way I could contemplate being laid-up during a busy time such as the sheep-shearing season in June.
"It's hard work and involves a lot of bending and lifting, but you get on with it and keeping mobile does help tackle any potential problems."
Mr Pugh, a member of the National Farmers Union of Wales (NFU Cymru) who supports the current Welsh Backs health initiative, added: "We are all different, but as far as I am concerned the advice is to keep active and keep busy."
The Welsh Backs Government campaign to help the Welsh nation fight back troubles is a joint initiative developed in response to Health Challenge Wales. Welsh Backs aims to reduce the physical burden faced by more than two-thirds of the population of Wales who will at some time suffer from back pain.
