chunking

i never knew that certain things were grouped together in certain numbers, in order for us to be able to remember them. apparently, we remember things better in groups, or chunks, of 7 give or take 2. that would mean phone numbers, organized with seven digits (not including the area code); zip codes, 5 digits; and anything else that groups 5-9 things together is done so in order to obtain a space in our brains. its amazing how many things you realize are chunked in order for you to remember them.

here's an everyday example. may seem a little simple, but it just shows how easy it is to apply the concept of chunking.
