You are invited to your cousin AJ Jacob's family reunion!

A.J. Jacobs (shown here with his [very distant] cousin Olivia Wilde) and a group of researchers are building the world's largest family tree. To celebrate, A.J. is holding the world's largest family reunion, and since you are related to him you are invited!

Tickets are on sale via Indiegogo for $25 and the proceeds will benefit Alzheimer's research.

On June 6, we're throwing a wildly fun, star-studded, worldwide festival to celebrate our interconnectedness. ALL MEMBERS OF THE HUMAN FAMILY ARE INVITED. GET LIMITED TIME DISCOUNT TICKETS HERE! We've got more than 30 great speakers (Henry Louis Gates, Dr. Oz) and amazing music (Sister Sledge is singing "We Are Family"). Bring the kids! Bring the cousins! You'll play games, join contests, eat food from around the world-and more. The main event is in New York City, but it will be livestreamed to dozens of simultaneous parties around the world.
