Research currently underway is testing the postulate that cultural jet lag stems from an atypical crystallization of the super-ego during the child developmental phases.
The common term jet lag is used, because before the arrival of passenger jet aircraft, it was generally uncommon to travel far and fast enough to cause jet lag.
The term debt-lag is similar to jet lag in that both have to do with travel, however travellers can be affected by debt-lag without leaving their time zone.
