I can't say how many times my fatigue and my speech disturbances even in my twenties, the speech would come out when I developed tics from some flares and things.
More and more, adults are sprinkling their speech with the language of children. The adoption of some of these linguistic tics by adults has given rise to a register we might call kidspeak.
Simple tics are relatively short in duration, lasting milliseconds, and can include behaviors like eye blinks, which would be motor, or throat clearing, which would be verbal.
