Hope your right Johny,lets not forget that these people are all very rich and potentially could be easeing into retirement by taking on a responsibility that is not as stressfull as the post they just left.It could be fun in their eyes to do this and if it hits they are rewarded and if it doesn't or takes longer then anticipated they are not going to loose sleep over it.
Before you all jump on me for being negative I'm simply giving a point of veiw based on investing in companies in the past that boast about the great retired or close to retirement talent they have added to their respective boards.
Cheers Jack
