I dunno man. Out of thousands people who commit suicide everyday vast majority were fluent speakers. Being able to convert your ideas into air vibrations aka sounds does not guarantee a perfect life. I used to think that fluent speakers do not appreciate how lucky they are not to have this impediment however if healthy people would start doing why should they stop at stuttering? What makes us more important than other challenged people? Everyday they should take a medical dictionary start with A, "oh I'm so lucky not to have Aids" and end with zika virus. That would take significant percentage of their lives. Yes fluent people have simplier lives in some aspects but not necessarily happier lives.
