Worried about a friend......?

A friend who i am chatting with over MSN (and he's really into astrology) told me that he is scared as he thinks he is going to die, because Pluto transmitted his 12th house. That was some 5-6 days ago, and i haven't seen him online for 2 days now......do you think he's............geez, i hope not, i can't believe that seriously.
