motion sickness? more like sleepiness....

i guess everyone would hv heard of motion sickness rite? but anyone heard of "motion sleepiness"?
seem like whenever i get on any form of transport, i will inevitably fall asleep....
since during my ns... in the bronco(i sit somewhere near to the engine!).... or in the bus.... when the vehicle starts to move, "周公" will come find me "下棋".
it it juz fatique or some strange habit? i am still unable to comprehend.
tomorrow is my off day.... if xiu nv call me, i guess it will be spring cleaning my room for the day.


::::to myself::::
