A quick post today as we have just heard that my wife's brother has died, so things are a little difficult.
I was watching UK BBC television and a show called Bargain Hunt. It's about two teams of two people who go out looking for antiques to try and sell at auction for a profit. Both teams are given £300 to 'spend' on the items of their choice.
Anyway, at the end of the show it was discovered that one member of each team had exactly the same birth date. This often happens, but then it also turned out that the remaining members of the opposing teams also had the same birthdates and, what's more, it was their birthday on the day the show was being filmed.
It would have been interesting to have found out if the two teams also had other connections as well, odds on they would have had.
P.S. In any group of 23 people the odds on having two people with the same birthday is 2 to 1 - a 50% chance. Full details on Wikipedia here.
