ARTelevision, have you ever read John Clancy's
Rainbow Six? In it, people use bio engineering to create a very potent strain of Ebola with the express purpose of killing off most of the human population. Reminds me of your first post in this thread (I just started reading it myself).
I've always figured, live each day to the fullest and enjoy what we have. Never know when your stay on this Earth might end.
Though, truly being positive in the face of bad news would be my cousin Linda. A year and a month ago she went to the doctor to have a lump in her breast biopsied. They said they'd call her if there was a problem. No one calls her so she thinks she's in the clear.
A year later she goes in for her annual check up. As it's ending, she asks what the results of her biopsy were... they look... oh hey, check that out, positive for cancer... oops. Oh, hey look, it's spread... joy!
So much for early detection eh? Things look mighty grim for her at the moment but she is refusing to give up. She just had both her breasts removed and is getting chemo/radiation therapy. Still, she refuses to let it get her down. Linda is still a warm, loving, outgoing and giving person in the face of adversity and bad news.
Stay positive, it makes the time you have in life that much nicer
