One thing a spy really needs is a good memory. Here's how to improve memory. Remember, not only good for spies...
Spies need to have a great memory. There are a number of reasons for this:
So a good memory is a spy's most used weapon. In fact, even if you're not really a spy, but say, a student, or a manager, or an adolescent, a good memory can help you in life. A good memory can be a life saver when studying for an exam or when you're grilled during a sales presentation.
So, how to improve memory?
If you regard your mind as a muscle, then it's easy to understand that training is key.
An average mind can hold a maximum of 7-10 items in short-term memory. A simple way to train your ability to memorize items is to let someone put 10 items under a blanket. Then, you get 30 seconds to study the items before they are covered again. Now, are you able to recall all items under the blanket?
Practice this often, and you'll see a dramatic improvement in your ability to memorize. But this is just one simple method.
Another method is to group items together. This works especially well with numbers. For instance, if you have a number of 10 figures 8 5 4 2 9 7 0 0 2 2 8 3, remembering each individual figure is much more difficult than if you group two items together: 85 42 97 00 22 83.
Why is this?
Remember that I said that the average mind can hold 7-10 items in short-term memory? For your memory, each digit is considered an individual item. 10 digits, 10 items. But when you group them together, it magically turns into 5 items: 85 42 97 00 22 83. Much easier to remember.
Another way how to improve memory is by association. With this method you associate the things you want to remember with things you have already put into your long-term memory. The idea is that it's easier to retrieve associated items, than totally unrelated items.
When you train your brain regularly, you'll remember how to improve memory!
