I'm a gamer and I prefer violent gore games when playing on my computer, I think that affected that way I speak and treat others in a more aggressive way and IT's really not a nice change.
It's 3 in the morning now in my country, and I am wide awake replying to your post, and I have to go to work later at 8am! I am really addicted to social media and whatever online. I use the computer at work and at home. I am pretty sure it has a huge negative impact to my health. I normally get only 3-4 hours of sleep everyday and it's taking its toll on me. My vision gets blurry at times and I just don't feel as healthy. I really need to do something about it, I know.
