How nice if we can buy more memory

How nice if we can buy more memory chips and insert into our brains so that we can remember more things? Just like our computer, when it is running low on memory, we can buy memory and make it run more efficient and faster.

Unfortunately, we cannot do that. We tend to forget and we seems to get more and more forgetful as we aged. Now, I have difficulties remember some of the things I just read or hear. The frustrating thing is sometimes, I even forget some of the things that took place years ago.
