“A woman was born in 1975, and died in 1975. She was 22 when she died. How is this possible?”

This is more of an exercise of imagination, considering a definitive solution to this does not exist. Possible solutions:

• “1975” refers to something other than a year in the former instance (ward room number etc.) -> she was 22.
• “1975” refers to something else in the latter instance -> she was 22.
• She was “too-too” when she died -> she was 0.
• “22” refers to something other than “years old” -> she was 22 weeks; seconds old etc.
