Two years ago, extreme Taylor Swift fan Ronnie Brower was told by doctors he most likely wouldn't live past 35. Why? Because Ronnie weighed 675 pounds. His old high school teacher, Joe Bufano, made him a promise: if Ronnie lost 425 pounds; Bufano would buys tickets and bring Ronnie to go see Taylor in concert.
The challenge was accepted.
And two years later, achieved!
