In 1982, Dr BS Ajaikumar was backpacking through Rocky Mountains, thousands of feet high, when a scream rented the air. His friend in the group had lost his footing and rolled down a few hundred feet. The rest quickly retraced their steps and carried the fallen trekker through a snow-filled trail, with ice picks. “It was dangerous, but we made it. Now I think it was one of the most exciting and interesting memories, because that was the first time my wife had joined me on a trek,” says the founder, chairman and CEO of Healthcare Global, laughing.
