First Degree Frost Bite, First Aid at the right time and this image was possible

We were on our way to Chuchul, the place where the Indian and Chinese Army recently clashed. We were driving close to the Pangong lake when we came across a frozen stream. We were driving on it and the car started drifting like a rock on ice. We stopped to dig some ice and put some sand on it for the vehicle to get some grip. While this was happening we noticed a flock of birds in the neighboring field. They were the Tibetan Sandgrouse. The temperature then was -20 deg. cel. The birds were so numb due to the cold that none bothered flying away on seeing humans at close proximity. We immediately had our cameras out and photographing the birds. As we clicked, I realized our hands were shaking a bit too much due to the cold. We barely managed to focus the images. But persistent, we continued to shoot. Soon I felt, my fingers going cold, swelling up, going numb and then start hurting. We had to then bolt to the car which by now had crossed the ice. My gloves had to be almost skinned off from my fingers. The fingers which were red then started turning blue and then towards black. We had the right medical back up and first aid that helped me revive my fingers. 
When people back home asked me if it was worth it, my answer was- Totally!!!
