have you ever been in a situation that demands your life?
Speaking of life and death situation;
Once upon a time while snorkeling off a Tropical Island (Pulau Tioman in Malaysia), I underestimated how strong the under-current was. I was swept down and out towards open sea. Only my most determined will to live saw me swimming frantically towards the boat while trying to get the attention of my guide to rescue me.
What appeared to be a couple of minutes in desperation, seems like an eternity.
