Sister Rachel Denton's twitter page is shown on a computer at St Cuthbert's Hermitage in Lincolnshire, north east Britain August 24, 2015. Denton, a Catholic hermit, rises early to tend to her vegetable garden, feed her cats and pray. But the former Carmelite nun, who in 2006 pledged to live the rest of her life in solitude, has another chore - to update her Twitter account and check Facebook. "The myth you often face as a hermit is that you should have a beard and live in a cave. None of which is me," says the ex-teacher. For the modern-day hermit, she says social media is vital: "tweets are rare, but precious," she writes on her Twitter profile. The internet also allows Denton to shop online and communicate with friends. "I am a hermit but I am also human." A diagnosis of cancer earlier this year reaffirmed Denton's wish to carry on a life of solitude, prayer and contemplation.
