There is not one man or women on this world who would not want to get smarter, seem smarter, But does it really matter?
For these people, it actually makes all the difference. Intelligence can be of two types, crystallized, which is the method by which information is stored in the brain; and fluid, which is the ability to learn and think critically.
It is this fluid intelligence that most people should worry about working on and improving and of course there are many ways in which this could be easily done. To sharpen your fluid memory, one of the many things that you can do is training you memory by using strategic activities thereby targeting the brain's weak memory corners.
Meditating and napping at regular intervals also helps sharpen your memory in a big way.
