May Go to Kelantan on Saturday

I came back from KL recently and now my colleague told me we may have to go to Tanah Merah in Kelantan to meet up with a client. Most likely it will be this Saturday. I am enjoying my work even though it requires constant travelling which I am getting used to. People complain of jet lag, not moving in the plane for long hours, but I wonder have they actually experience car lag? I guess it is different then as there is more space to move around compared to a plane.
