To continue on your example; a 'fat' person is medically unable to become non-obese; simple because there is no way to remove fat cells, except by surgery; you can only temporarly remove the fat from the fatcells. Similarly we are stutterers for life; and that is neither good nor bad. But just as someone obese can live a healthy life; we can live a healthy stuttering life. Edit: as a fellow stutterer; please refrain from implying stuttering should be concealed.
