Here's a timeline app at the Atlantic that pulls up facts and trivia based on your age. It could make you feel old, but should make you feel nostalgic. Or, if you're young, it could just be boring. Enter your birth date to get started. Here's part of what came up for me.
At 10 years old, you were alive to behold people walking on the moon.
You're one of the first people who's never lived in a world without The Cat in the Hat.
Around the time you were born, Jack Kilby demonstrated the use of his invention, the first working integrated circuit.
Each fact also has links to Atlantic articles about the same subject. You can add or subtract a few months to get different facts, or enter a random date to see how different it is for people of different ages. -via Nag on the Lake
