we can only multitask via task-switching
That's my day. Jumping from crisis to even more urgent crisis and back again over and over. It's expected. If anyone was only able to do one thing at a time, they'd not last long here. Priorities shift, often by the minute. You could be halfway through analysing half a million rows of data diagnosing an issue then dropping that, diving into source code for something else, drop that to have a quick meeting to agree a design point, back to the source code then back to the data, and that's within a 30min window. I'd say I have a lousy memory but I'm still expected to jump about and pick up where I left off.
