What is more revealing, however, is that of the 654 sent back to China, 12 per cent were addicted to opium (a percentage that had risen markedly during their stay on the Rand) and an extraordinary additional 22 per cent (by far the biggest category of ârejectsâ being returned to Asia) were said to be suffering from social maladies of one kind or another - close to one in three. And of those 143 âsocialâ wrecks, no fewer than 83 were said to be suffering from âsenile delayâ or were deemed to have become âmentally deficientâ or âhalf-wittedâ. Another 23 were considered to be engulfed by a âweak-minded maniaâ, âviolentâ or just plain âinsaneâ. Even when one considers the possibility that at least some of those suffering from these âsocial disordersâ might have faked or exaggerated their symptoms, one would have to ask what drove men to take such desperate measures.
