Windows into tomorrow Book

This is a book of short stories that I read as an adolescent and just kind of latched onto. It is full of stories from every "mood" and really gives you a taste of lots of different kinds of science fiction. "Death is an Acquired Trait" is my favorite story in the book. Ever thought about immortality? You'll never think of it the same if you read this. I also really like how he leads you to make certain assumptions about his characters and turns them on their ear, or comes up with unexpectedly funny situations to write science fiction about. I liked that it had such a great mix of thought-provoking and amusing stories.
