To find information and read the topic i am interested in because there are so many magazines and we always have opportunity to pick one in which we have interest. Magazines builds an hobby in person as well sometimes.
I usually always take a magazine with me to the Outhouse as I like to read and take my time. But they can come in handy if I'm out of TP also !
The magazines I get are specific to my interests, photography and travel. It not only gives me info to things I want to know about, but they give ideas for things I never thought about.
