Actress Miriam Margoyles has revealed she can no longer walk and fears she will need a wheelchair soon.<br /><br />The Harry Potter star spoke of her regret at her previous lifestyle choices as she struggles to walk due to spinal stenosis.<br /><br />Speaking on the How To Fail show, Miriam said: "The one thing I have not conquered and should have conquered is my weight. I am a blubber mass. I am fat. And to be fat and 82 is truly pathetic."<br /><br />“It’s such a defeat. A cream bun, a chocolate, or a helping of chopped liver is more important than your health and aesthetic presentation? No it isn’t more important.”
