THE posthumously published autobiography of science fiction master Isaac Asimov reveals that the "I, Robot" author died of AIDS. Due out later this month, "It's Been a Good Life" - which Asimov's wife, Janet, compiled from her late husband's notes and essays - details how he contracted AIDS through a tainted blood transfusion while undergoing bypass surgery in 1983. He finally succumbed to the disease in 1992, at age 72.
