Seeing Qin Ruan's satisfied expression as she ate the pickled plum, Qin Mei, who was standing nearby, couldn't help but notice.
He could still taste the sour and refreshing plum in his mouth, even salivating a little.
Don't get me wrong, this wasn't out of greed, but rather a conditioned reflex, a high-level neural activity controlled by the brain.
This kind of reflex is enhanced by continuous stimulation from the same signal, and the longer the reflex lasts, the more intense the feeling becomes.
If the reflex doesn't continually get reinforced with stimulation, the feeling will gradually fade away and eventually disappear.
Qin Mei swallowed his saliva and took his gaze off Qin Ruan.
He was afraid if he continued watching her, he might actually start drooling.
Meanwhile, Josh had no reservations about opening his yogurt and started drinking it.
That first sip, nearly choked him.
"Damn it! Why is it so sour!"
