TV presenter Kate Humble has revealed that she went three weeks without washing while filming a new BBC documentary.
The former Springwatch and Volcano Live star, 44, lived with traditional shepherds in the remote mountains of north-eastern Afghanistan while recording the BBC Two programme.
She told the Radio Times: "I slept in a yurt with eight men for three weeks and didn't remove a stitch of clothing, or wash anything, the whole time I was there."
Commenting on the livestock herders that she lived with, she said: "Their life is unimaginably hard, but they are so dignified and proud of their heritage. It was a privilege to spend time with them."
The presenter's journey in the show, Wild Shepherdess With Kate Humble, ends in Australia where the science of cloning and genetics is being used to produce "super flocks" of sheep.
Kate told the magazine: "The science is fascinating, but it's slightly depressing that it's only advancing because of our greed: our need to eat meat all the time and buy it at an absurdly low price."
