The most unusual (and visible)

The most unusual (and visible) aspect of betel chewing is its effect on the salivary glands. You don't just salivate, you pour; and the saliva emerges from your mouth tinted a deep brick red. (...)

Perverse as it may sound, betel-drooling is quite pleasurable indeed. There is an almost orgasmic satisfaction to be found in the experience of saliva-ducts open to full throttle. Delicious above all is the aftermath: when the chew is finished, your mouth is left astonishingly fresh and sweet. You feel uniquely cleansed, drained, and purified.
