I remember meeting N Chandrasekaran, then CEO of Tata Consultancy Services, after a post-earnings interview sometime in late-2009 or 2010.

At the end of the conversation, my colleague asked him what he did to unwind.

Chandra, as he is best known, spoke about a recent trekking holiday (Nepal, if memory serves right).

The trip lasted about a week.

Anything longer than that, Chandrasekaran said, and he would get restless and want to get back to work.
