Memory Retrieval Device

Many times, such as now, I find that I've lost all of those wonderful ideas I had earlier in a day, week, month, lifetime. Somewhere these are hidden in my brain, having been passed over fleetingly at the time of their conception as no more than random wonderings. If only I had some way of retrieving these thoughts I could make a much more exciting contribution to things such as this website. Maybe something that records all your thoughts for review at your convenience, or a drug that would stimulate the correct memory cells for the type of information you're looking for. Of course this would require a somewhat more extensive knowledge of the brain than we have now, specifically it would be helpful to know which cells do what and how to stimulate them correctly. I suupose this would be bad if anyone wanted to get information out of you, but that wouldnt matter if you didnt get into those sorts of situations anyway, now would it? Anyway, I guess I've had an account here for a while and thought I should at least explain why I've never made a contribution, mainly because I'm lazy but also because I have no memory. Oh, and it's my brother's birthday today. That has nothing to do with anything. (If this idea has already been posted, sorry. I haven't exactly read everything on this site)
