How many ways can you say tired?

I was thinking about that this morning driving my son to school. I realized that I was feeling kind of tired. But, the kind of tired I was feeling this morning, with an ache in my shoulders and scratchy dry eyes, was different from the kind of bone crushing, disorienting tired I felt last night after I had spent two hours making revisions to a web site. The kind of tired where you can't think straight and when you run into a html programming glitch trying to upload files, your brain just kind of freezes and you blank out as you struggle to remember how you resolved the problem the last time it occurred. Now this is all together a different kind of tired from the tired you feel when you are just bored. I have a theory that, many times when asked how they are feeling, people just say that they are tired because they are completely and utterly bored and just don't have the creativity to come up with a different adjective. Then there is the tired you feel after the physical exhaustion of stepping up and down on a riser for an hour or the tired you feel when you try to run on a tread mill for 35 minutes and have trouble picking up those heavy feet. Or there is the impatient tired you feel when you can't find the "off" switch on your six-year old and the questions just seem to keep bubbling out of his mouth. You struggle to clear your head and concentrate and form a coherent response as to why the air gets colder as you go up into space instead of hotter since you are getting closer to the sun.

I think that I need to create a new language for tired. The eskimos have something like fifty different words for "snow". I think I need to create fifty new words to describe tired.
