they hit the threshold of loss, they will not play anymore. I will attempt to define threshold of loss as regards gambling as the minimum intensity at which a gambler can no longer tolerate a loss.
Man, for many gamblers such "treshold" is the same as "lose your flat, your car and your wife"

Because many people are addicted to gambling, like drug jankie. So for them "tershold of loss" does not make any sense.
My question is, can you remember a time when you reached your threshold of loss while gambling?
I havent reached it yet, this for the good I think.
