If we all die and there is no God, then it's just eternal unconsciousness, you'll never know, but if you're wrong. . . you'll know forever.
I was playing in the juniors at Wimbledon I forgot to turn my mobile phone off. It was lying there in my bag and it rang in the middle of a match, and it was one of my friends from school saying, 'Murray, you're on the telly!' I learnt from that. After that I always put my phone on silent.
