Dr Amir Khanis an NHS GP and woman&home's resident doctor. He sees patients in his office every day, and when he does, he's not thinking about whether someone has lots of visible muscle or "looks fit". "[I'm thinking] 'can you get out of a chair easily? Can you climb stairs? Can you stop yourself from falling? Can you carry shopping? Can you stay independent?'" he says.
