&gt; Most people don&#x27;t produce language in the same amounts that an interpreter will<p>It isn&#x27;t really because of how much they sign (deaf people don&#x27;t typically get RSI from sign language), but rather because of <i>how</i> they sign it. The signing is more precise and formal, the hands&#x2F;arms are elevated more, and generally less &quot;colloquial&quot; than you would see in day-to-day sign language.
