worry about shit like what preservatives and chemicals and shit are in the meat you eat.
worry about what chemicals and shit are in tap water.
worry about what subliminal messages you're being exposed to when you turn on the tv.
worry about whether the government is monitoring what you're doing on the internet.
etc etc. All that paranoid bullshit (not saying it's not real. Moreso just who gives a fuck?)
The question is, do you think that by worrying about all that shit and adjusting your actions and lifestyle in accordance with what you know (or what you THINK you know), you are actually improving your health and quality of life?
