I often find, if I am careful, that memory hovers around various activities during the day and can be left there and returned to. For instance, if I'm stretching and thinking about something and the phone rings, I get up to answer it and forget what I was thinking; but if I return to the same place and the same stretching movement the thought is there waiting.
With some experimentation this turns out to work fairly well as a way of multitasking, so long as you move about between tasks (thinking of something for your work in one space; taking a break in another).
It's a very curious thing to play with. Does this sort of thing work for anyone else?
