Natasha Richardson has died

This is very sad news. Natasha Richardson is part of the very famous Redgrave family, and indeed married to Liam Neeson.

This is a personal tragedy to the whole family, particularly her children and husband. I am very sorry for their loss.

This all started with an innocuous harmless skiing accident causing no apparent injury bar a bit of a knock to the head. It just goes to show how dangerous head injuries can be, and how hidden the real damage can be.

The BBC has this.
