On the 7/7 thing, I know of someone whose life was SAVED because of 7/7.
Colleague at work's sister was depressed, pretended she was going to work and set off, waited til husband had left home then let herself back in and took a massive overdose.
7/7 happened, husband couldn't get hold of her, so called her work to see if she'd got there ok and they said no she's on annual leave what do you mean?
Husband suspected the worst rushed home and found her in time.
Now I don't believe that's anything other than a random coincidence but its nice to think that a life was saved on that terrible day.
