Short answer: Family tragedy at a beach at the south of my country. My mom, little brother and cousin almost drowned.

I was 14 and had no training. Only a cheap bodyboard, and knew how to swim. I managed to take my brother and cousing back to the safety of the beach, but they wouldn't let me go back to the water and take out my mom. The waves were huge. The current didn't want me to move in any way I wanted. But I was able to save two out of three.

(It was a beach with no lifeguard, being in the south. In the end, firemen saved my mom.)
