Sunil Dutt (passed away yesterday) was recovering from an accident that had paralysed half of his body... "For two months, I could not get up from the bed. But I always wore a smile for visitors. They would comment hesitantly, 'It doesn't look like anything is wrong with you'. I would grin in reply, 'My lower half is immobile. My face is not, so why should that stop me from smiling?' "
