Human fixation with so called significance of numerical coincidences has always bemused me.
However, put it into a different perspective by using metric instead of avoirdupois:
US baby born on 9/11 at 9:11 weighs 4.394 kgs Not quite the same!
As a fisherman I could never understand the significance of 20lb - a 9.07 kg carp just doesn’t have the same cachet!
As for anniversaries, don’t get me started! Why, oh why, are we so fixated on 50th and 100th anniversaries? I wonder sometimes if they are inventions of the ruling classes - give the masses something to celebrate and be happy / sad about and it will divert their attention from all the s**t in the world. Or am I just being a cynical grumpy old git?!
