I think it's important we all jump through hoops to live our lives the way health and safety experts tell us to. You know, don't do anything they say is "bad" or "wrong," otherwise you can never be happy. So on that note I thought I should share some serious concerns. What you should do is freak out and base your life decisions and general outlook on this type of stuff. The important thing is to conform, and don't get stressed cause that's real bad for you.
