And unusual Deaths in 1990:
Joseph W. Burrus, aged 32, an aspiring magician, decided to perform the "buried alive" illusion in a plastic box covered with cement. the cement crushed the box and he died of asphyxia.
George Allen, an American football coach, died a month after some of his players gave him a Gatorade shower following a victory (as it is tradition in American football). some argue this resulted in pneumonia.
Amazing how when you're celebrating life, people are dying.
