Mankind has created spectacular works of art, engineered incredibly tall buildings, designed impressive supercomputers, lived in outerspace, discovered cures for nasty diseases. As a whole, nothing can compare to human intelligence, but sometimes, humans don't live to kiss and tell.

Lover to die for kiss-and-kill pill

A Chinese woman who killed her lover with a rat poison-laced kiss when she suspected him of being unfaithful has been sentenced to death, a newspaper said Thursday.
 Xinfeng, from Maolou in the central province of Henan, passed a capsule with rat poison from her mouth to her long-time lover, Mao Ansheng, during a kiss, the Shanghai Daily said.

Mao swallowed the capsule and died soon afterwards.

"The couple had said that if either one of them cheated on the other, he or she would have to die," the paper said in explaining the mouth-to-mouth assault.

Xia found Mao had been "talking" with another woman and deemed that he had broken their promise.
