In 1987, Oprah Winfrey predicted that by 1990, 20% of all heterosexuals would be dead of AIDS.
I think she meant all heterosexuals in the U.S., or maybe she meant in the world.. Either way, it didn't pan out.
The heterosexual AIDS epidemic is yet another one of those failed predictions, which it is considered impolite to mention.
Similar to how the world would run out of oil by the year 2000. Remember that one?
