Nicolai Calabria has already become one of the best 106-pound wrestlers. He has successfully climbed to the top of the highest mountain in Africa, and most importantly, he's changed the attitude of any normal person who watches him compete.

The 17-year-old teenager has one leg. He was born that way, but his goal is to show it's not the one thing that defines him. He would also be the first one to tell you that he just wants to prove to others and himself that he's just like other normal ones.

When Calabria was young, his parents tried different prostheses(假肢)to find out which was most comfortable for their son as he tried to keep up with a family, who has a preference for sports.

At first, the Calabrias had their middle child in a prosthesis that looked and functioned like a “real” leg, but soon they decided to choose a different path when they found it wasn't beneficial to his movement. Then the family moved him to arm crutches(手杖) and from there a new burst of energy was found.

Getting others to believe that he could take off on the soccer field took a little bit longer. When the Calabrias moved to Concord, they had a hard time convincing the town soccer program to allow a child like him to compete with able-bodied kids. After months and months of debates and meetings, the family received the answer they were looking for. Since then, witnessing a young man on crutches who competes against those with two legs has become a fixed event in the Concord community.

“At that time I had nothing but discouragement working with the soccer community, however, now I have nothing but admiration for the fact that he's been allowed to play, and people see that he adds value to game，” his father said, “I just think it's a great result.”
