I fly a lot during the spring and fall as I travel to speaking events.
I often try to talk to the people sitting next to me unless they are enveloped in a cone of silence, AKA headphones.
On one flight I was sitting next to a network engineer who helped run the IT department at a large company.
As we talked about his job, I asked him if it was stressful. He was in charge of a huge network, the technology was changing constantly and it seemed like he had a lot of demands on him.
