There is a famous quote from Douglas Adams:

Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works. Anything that’s invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it. Anything invented after you’re thirty-five is against the natural order of things. Apply this list to movies, rock music, word processors and mobile phones to work out how old you are.

These feelings are just the cohort of which we are a part getting older.
