Astronomy or astrology?

Do you know the differences between astrology and astronomy?
Most people think that theese two science are the same, but the truth is that astrology isn't an real science: its a psuedoscience, a knowledge that isn't based in the scientific method, like people that set that they could know the future with cards, and most of the time they're trying to get money.
By the time, astronomy its a real science that studies stars, planets and the universe in general.

Problems caused by social media

Every day the media reports on models and sportsmen who have a thin body and this causes problems, especially in teenagers. This problems are basically nutrition problems like bulimia and anorexia. 
This problems are caused by psicology problems, that make a person think that he or she is fat and because of that, the person doesn't eat much food or eat a lot and then he barfs it. 
This problem is increasing every day and i think that social media must tell more often about healthy habits and less about famous people with perfects bodies.
