Keira Knightley caught pleurisy through over working. The actress was struck by the lung problem last year - characterized by pain when sufferers breathe - but at the time thought she had just hurt one of her ribs.
She said: "You do period films and you get some sort of weird archaic disease. And I didn't realize, so I went on for another month. I just stupidly never went to a doctor. I was rehearsing for this play and then I found in rehearsals it got so bad that I couldn't stand up any more. And they said: 'Please, can you go to the doctor?'" The 27-year-old star has since turned to yoga to help keep her limber and functioning, but that has also resulted in a few injuries. She told the Australian edition of Harper's Bazaar
: "My body at the end of
last year was breaking and I thought, 'I've really got to try and do something.' I've been trying to get myself into gear. I've been doing yoga, but I've already got injuries - from f***ing yoga."
