This great man, Steven Hawking, needs to be listened to for a change!!!!
Instead of holding up politicos and sports stars to the youth of America as "heroes" THIS man fits the bill. Intelligent, witty and a role model for us all.
The above link connects to a story from England about what he thinks Mankind needs to do to survive.
I've read all of his books and he has a lot to say :if only people would listen.
