When I'm programming?
I eat nothing, I drink water or coffee,
and not I'm listening to music then.
My music is very intense, and I listen very carefully to it, I won't do anything besides it.
When I eat, I eat good and tastefull, and I won't listen to music while I'm eating.
I am very intense, but I am quite easily distracted. When I'm programming, I usually do not stop until the early hours, completely exhausted :-)
