>According to Provine, there is some historical evidence that tickling was used as a method of torture and execution in centuries past. In one reported and exceedingly bizarre technique, a victim was tied up and the soles of his feet were covered with salt. A goat was then brought in to lick the salt, causing intense tickling. If kept up for long enough, the stress and exertion of laughing – and squirming – could have eventually brought on cardiac arrest or a brain hemorrhage.
