The age where you realize you are closing in on thirty. Also, the age when you realize that you are no longer a young adult, but a real adult. This is the point where you know if you have done nothing with your life, you better get crackin. You can still have fun at twenty-six, just make sure that you take care of your priorities because it's better to be a loser at twenty-six then be a bum at forty.
My friend just turned twenty-six and realized that she has nothing to show for it, not even a car.
