Ans. In 1992 Santosh was on Everest Mission. She had got a team of climbers along with her. All of them were proceeding up on their expedition to Mt. Everest. One of the climbers slipped and fell down. Hemet with serious injuries. She provided special care to that climber. But in spite of her vigorous efforts she couldn't save his life. But she managed to save the life of another climber, Mohan Singh, who would have met with the same fate, had she not shared her oxygen with him. She did not hesitate to provide him her oxygen, without caring for her own life. It is an extraordinary example of her greatness and sacrificing attitude.
