Old Fartdom

Many years ago my grandmother said to me that she still feels the same as she did when she was a teenager, and when she looks in the mirror she is shocked to see an old bag looking back at her. I remember at the time, I was in my early twenties and going through that "I love getting older and wiser" bullshit phase, being surprised by such a comment.
Last night my older stepson, who lives with his mother, brought his new boyfriend around for us to meet. The newboyfriend was very sociable and took an interest in my DVD collection, stating he liked horror films. I also love horror films and told him I have a collection of "old school" stuff. The click of the generation gap kicking in was almost audible. My "old school" is Vincent Price, Boris Karloff, Hammer etc. He asked if I had the original Hellraiser. I was baffled. Why would I have Hellraiser? That's not old school. Oh, wait a minute…Hellraiser was made in the mid 80's…before this young man was born. To me, the 80's are modern. I think it's time to review my chronological perspective.
And could someone please tell me…who IS that old bag in the mirror?
