A lesson from dad helped an 11-year-old New Hampshire boy save his friend's life.

Jack had just recently learned the Heimlich from his father and was quick to show his mom that he knows what to do if he needs to save a life.

Luckily, Jack was there when Bella needed to be saved.

"I swallowed it and I tried to cough to get it out and I tried to swallow it, but I couldn't swallow it, and I was trying to say, 'Jack, help me,'" Bella said.

"See mom, God wants me to save," Jack said.

Jack and Bella, who have been best friends since second grade, surely now share a very special bond.
