I do not. The only things that stay in my brain are some common underlying principles. It was like this in university and the academy of science when I was in physics. Now it is in the programming. If I need to know particulars search is my help. I program very different things from firmware to desktop applications to enterprise backend servers in multiple languages. If I had to keep all those details in my brain it would explode. Usually it takes me a couple of days to warm up when I am starting work in the area that is not in my "hot cache" and then I am fine but the other stuff gets purged accordingly.
