What is a 76 year old doing climbing on the roof of a shed to do work. I imagine he was comfortably well off financially get someone in !! Reminds me of Rod Hull who died climbing on his house roof to sort out an issue with an aerial and fell to his death he was younger at 64 but clearly no spring chicken . Is it non-acceptance that they are older , the "I've always done this so I still can" syndrome .
