I hope you are feeling better.
As for those moments when I feel old, I have had a few of those.
Years ago I went to lunch with a group of people at the office one day years ago. Most of them worked for me directly or indirectly, some are newer hires in their 20s. So we crowded around a high table at the bar and ordered food. Several TVs in the bar and out of the corner of my eyes I noticed they were reporting something about Paul Newman. He passed away that day so this is over ten years ago. I mentioned to the others that Paul Newman died, everyone looked up at the TV where they were showing his picture...and not one knew who he was. I asked if they had seen The Sting, no? Cool Hand Luke, no? Butch Cassidy...The Hustler? The Color of Money, no? Hmmm ok...then one girl had an epiphany and said "oh I recognize him", I looked at her and then she said "he is the salad dressing guy!!!" and others nodded in agreement oh yeah that's the salad dressing guy. I felt so old haha.
