I realised last year that I'd reached the age (48) that my mums dad was when I was born. I remember him "always" being "old", but I also know that I have memories of him from before he turned 55 (he took early retirement around then, and I remember clearly the discussions about what would happen to his workplace that led up to the offer of taking early retirement). He lived another 32 years after that, and all of my grandparents were young enough through most of my childhood and teens that not only were they around but they had the energy to have us stay for whole weeks during the holidays and take us all kinds of places... Meanwhile my son, at 14, has only one living grandparent, and it does feel weird.
