My maternal, beloved granddad lived to 97. He smoked heavily from the age of 13 until he was 94, survived a very nasty motorbike accident and a perforated ulcer, and after my granny died at the age of 62, seemed to exist almost exclusively on a diet of bread and cheese and Ovaltine. He was never overweight though and until around the age of 87 cycled everywhere.
It is incredible to think of all the historical events that lady has lived through. It seems like she had a good life. Mustn't it feel really amazing to have a 91 year old daughter!
