working hours for an engineer

A promising young NASA aerospace engineer was killed in a horrific car accident and arrived in Heaven, protesting to St. Peter at the pearly gates. "St. Peter, I'm only 35. I'm much too young to die. I have a wonderful wife and family, so much to live for. Why in the world am I here?"

St. Peter looked through a huge stack of papers, looked over the top of his glasses and said, "Well, according to all of these hours on your time sheets, you've got to be at least 108."
