For example my mom asked who the angry chef on TV is and somehow I immediately knew "Gordon Ramsay!" even though I don't have cable TV, never purposely worked on remembering his name, and am generally terrible at remembering names. Being able to remember things without trying is what most folks would really want when considering improving their memory.
I have found success with methods that call for imagining a 3d space and placing objects in that space and using it to recall things... However, designing such a space takes time/effort which is difficult when you're trying to learn and comprehend stuff on the fly.
I do wonder if it is a memory issue or a recall issue here...perhaps I actually know the information but can't access it as necessary.
