What we can do now is contribute to a clearer understanding of what happened that day on Everest in the hope that the lessons to be learned will reduce the risk for others who, like us, take on the challenge of the mountains.

Concerned that others were not coming onto the summit and because I had no radio link to those below me, I began to wonder if there were difficulties down the mountain. I made the decision to descend.

I explained I wanted to descend as quickly as possible to camp IV in order to warm myself and gather a supply of hot drink and oxygen in the event I might need to go back up the mountain to assist descending climbers.

I don't know what being an Everest guide means. I am a coach, not a guide.

The tech company needs to win in the war for talent. This means much greater focus on the employee, not simply as cog in the machine, but vital member of a programming team in a race against time and competitors. Wall Street is up-or-out, dog-eat-dog, survival of the fittest.

English football is very different, and I had to adapt to it much more than I would have had if I had stayed in the Russian league. But after a season, I felt a lot better, a lot fitter.

I always just take pride in being a basketball player.

For me, practice and discipline are the magic words to become big in any sport, especially soccer.
