Mentally tired is the worst, it affects my sleep. <br />
Physically tired, I just pass out dead to the world and sleep soundly.
Mentally can include physically
I don't like to be mentally tired, but physically tired knowing you have the next couple of days off is the best. Especially if it's for a good reason (i.e. hard work, exercise, or great all day sex).
Mental fatigue is cancer causing...nuff said,
I am both right now... to tired to fall asleep!
Mentally for me. It drives pple to their physical limits like running a marathon. But if you have a fit body but don't have any motivation, drive, then even getting out of bed would be difficult.
if you are physically then you can not work mentally.
Mentally. <br />
I worked at a government-run office once, and it was the most stressful job I have ever had. Every night I came home with massive headaches, stress, and mental fatigue. I gained weight, developed an ulcer, and got sick a lot. It was my most unhealthy time.<br />
I'd rather be physically tired- hard work is good for the soul and body.
Mentally. Your just "out of it."
i don't even know.. i have been both physically and mentally exhausted for so long that i cannot tell which is worse..
