About three out of every 100 births result in twins. It's pretty rare. But come graduation day at Norwin High School this year in Westmoreland County, Pennsylvania, 11 sets of twins will receive their diplomas. They tell us twin life at the school, located in the Pittsburgh suburbs, is special. Some of the twins are identical. Some are fraternal. "I didn't realize there was so many of us until I got down into the office and I was like, 'Oh my gosh, there's 22 of us,'" said senior Rachel Cassley."I thought it was normal, so I just think it's really cool," her brother Jack said.While the twins have a lot in common, they have different passions."Some of them do go to our (Central Westmoreland Career and Technology Center) to work in the technical fields," said Norwin Principal Michael Choby. "Some of them are athletes or are in the arts or leads in the spring musical. Some of them just came back from a field trip to Las Vegas about the Envirothon and recycling projects."Luke and Alexis Clamut say twin life is just normal life for them, and graduation will be bittersweet."I think we can all relate that, when we're going to go to college, it's just going to be hard," Alexis said, "because we just live together constantly and we've grown up together all the years and graduating together."So, do twins have special powers? "Not that we know of," said Emily and Allison Arendas. They do admit they sometimes finish each other's sentences. "If anyone ever asks, I can say, 'Well, I graduated with 10 other sets of twins in high school," Luke Clamut said.
