I have done two puzzle.
The first puzzle says: Two twins went into a bar. They drank the same drink. One of twins dranks very fast and another twin dranks very slowly. The twin who dranks slowy died and the twin dranks faster survived. Why? I didn't know the answer.
The answer is the ice cubes in the drink was poisoned. The twins who dranks very faster survives because the ice cubes didn't have time to melt.
When I was a little girl my mather say me: you must to eat and drink slowly. I understand it.
The second puzzle says: Alan and Carol are married. One day Alan fly to London at 8.30 h. His wife at the same hour she watch a film. The film is interrumpted by a new flash. The 8.30 plane to London has crashed killing all the passengers. She continues to enjoy her film. Why doesn't she react??
I Knew the answer: Carol is watching a video of a film she recorded the previous week.
I think your husband is very lucky, he caught the plane a week later.
