Ways to know you are getting old

After spending a week with my teenage cousins I learned that I am old...
  1. Snap Chat is explained to you, and you still are not sure why anyone would want to use it
  2. You make younger family members add you as friends on their various social media accounts so you can monitor what they are doing
  3. The Urban Dictionary app is installed on your phone, so you can translate the slang that kids are using
  4. Music you listened to in college is being referred to as 'old' by teenagers
    BTW I graduated college in 2008
  5. You turn a walk in a local park into an educational event
