I guess because your reading and reading is good for the mind.
how is newspaper better than watching television or listening to radio?
I would not say it is better - for me a mix of all the media mentioned above is important. And always compare what the media is telling you - there are many different ways of approaching a topic
You can read the newspaper on the toilet, then give it the respect it deserves by wiping your butt with it, you cannot do this with the TV or radio.
Newspapers are generally a better news source. Local TV news is worthless. I like listening to the news on the radio--. Judge the reliability of news sources for yourself. I think the key thing with news is to have more than one source of information. I have favorite liberal and conservative web sites. Be sure to judge the accuracy of what your chosen news source is reporting. If the stories they report as fact today end up being total BS tomorrow, you need to discard them as a source of information.
