I watch my immediate family of which I was not raised in and begin to wonder. My mom ( this is annonymous ) was ( was being the opperative word ) addicted to alcohol. My brother ( half brother ) younger than I am but still an adult, while he never did drugs or never even drinks, spends literaly about 20 hours a day on the internet playing everquest, only getting up to eat and sleep. My step father, ( brothers father ) was active in life till he was about in his late 40's, then went downhill into alcohol, and depression. I look at myself and worry about the same fate. I work, am a mother, but recently within the past several years have ran into many obstacles and hardships, and have temporarily been plunged into staying with my family, whom for the most part I have been able to avoid for a good majority of my life. I love them, but get along best from a distance. When I see them almost 24 hours a day, sitting in a constant cloud of smoke in a small conjested apartment, talking to friends they only know from behind an illuminating screen, I become so depressed , angry, and begin to worry if this may or may not be my fate as well. How far does DNA go? I know character traits are inherited, as are addictive personality traits. But to what extent? After all, it is proven that depression is hereditary? But where do we draw the line between depression, and sheer laziness? And is laziness itself a characteristic hereditary trait?
