Last year i was driving about for 36 hours.
Travelled , met persons , and return back. Everything took about some 36 hours. Didnt sleep any where.
Strange thing was at last part i was so sleepy.
Sleepy means , a bus over took me and went some distance. but the yellow board was still fixed my view.
Stopped , washed my face and back to my fav seat. reached home after some 3 hrs after this incident
DONT ever drive like me , nor will i do in future.
