Hi!the riddle of the sphinx was what goes on four legs in the morning, two legs in the afternoon, and three legs in the evening? (the answer to these riddle is "A man." As a baby, a human goes about on all fours ("four legs in the morning"; morning = childhood), until he learns to walk, which he does so well into adulthood ("two legs in the afternoon"; afternoon = adulthood), until old age requires him to use a cane to support himself ("three legs in the evening", evening = old age), finally he dies ("no legs at night", night = death).
