A Man In Ireland Saved Another Man’s Life Just By Asking One Simple Question

Truly wonderful.

When it comes to a simple photo, sometimes, the story behind it can be just as powerful as the image itself.

Photographer Peter Varga runs Humans of Dublin, a photo series page on Facebook that collects images and personal stories of people in Dublin, Ireland (similar to Humans of New York.) On Monday, Varga shared a photo on Facebook of a man who prevented a stranger's suicide -- and he tells the whole awe-inspiring story in the caption. The post quickly went viral and currently has more than 36,000 likes.

Varga's subject, a man named Jamie Harrington, recounts the story of when he helped another man in need. "I saw this guy in his 30s sitting on the ledge of the bridge," Harrington told Varga in the post. "I just thought, 'Wow...' I stopped and asked him if he was okay." Harrington's decision to interact with this stranger actually changed the course of his life.

"He said in that moment that I approached him, he was just about to jump," Harrington says. "Those few words saved his life. That they're still ringing in his head every day. 'Are you okay?'" Read the full story below.

Harrington himself has dealt with depression as well, having been diagnosed at age 13. He has spoke to SpunOut (an Irish youth information website) about his own personal experiences with the illness.
