When did you realize you were old?

For me, when CD's were the thing of the past. They don't even put them in cars anymore from what I understand.
Maybe this one; when you go to buy liquor or alcohol and you get carded and the cashier said you're good because there is a "1" in front tof the year you were born. Possibly this one; when you have to put your birth date into a profile or questionnaire online and you have to scroll down for your birth year like you're spinning the wheel for "The Price is Right". Who remembers what a cassette deck was?

Anyone remember these cellphones when they came out? Remember how we had to text? Goodness!
