Playing piano helps me a lot with reversing this fragmentation. It requires and rewards focus at the same time. It also shows me how much my mind is fragmented. You can get pretty used to this fragmentation such that it becomes your default state of mind that you don't question anymore.
The programmers among you will recognize the high price you pay when your focus is kept from coelescing, because somebody dumps a bunch of meetings on your calendar, or because you keep getting interrupted. A thirty second interruption costs vastly more than thirty seconds.
