Adam Klein is a huge fan of Survivor and managed to make it to Millennials vs. Gen X's two-hour finale that airs Wednesday night on CBS.

Adam is a 25-year-old strategic planner and manager for a non-profit homeless shelter from San Francisco, CA.

Adam, Hannah Shapiro and Justin "Jay" Starrett are the three millennials left in the game although they aren't necessarily working together. The Gen Xers who have survived thus far are Bret LaBelle, Ken McNickle and David Wright.

Adam is a well-rounded player since he's social and strategic. He also won an Individual Immunity Challenge, found idols and advantages throughout the game and made moves while recently staying under the radar.

Before entering Survivor, Adam said his fellow competitors wouldn't know the power of his punch "until they are already knocked out." That has turned out to be true! Want to learn more about Adam?
