BRUSSELS, Dec 19 (Reuters) - "Being disabled doesn't define a person," says Sarah Talbi, who was born without arms and has become a social media star with her videos on cooking, painting and other activities she is able to do thanks to the extraordinary dexterity of her feet."I wanted to show that there is nothing dramatic about being disabled," says Sarah, who appears in one YouTube video showing her audience how to cook a Maghrebi dish of eggs poached in a sauce of tomatoes and peppers, all done with her toes and feet."Thanks to the era of social media, we can exploit the power of images," Talbi told Reuters from her home in Belgium's capital, Brussels."Often we are treated like children," she told a European Day of Persons with Disabilities conference in Brussels last month, where she explained that many people post unpleasant comments and even mock her disability on social media.She started to draw and paint with her feet and, with support from a teacher, found she had a talent for watercolours, her toes curling as deftly as fingers would around the paintbrush as her other foot holds the paper still."
