I've also been getting to work pretty sweaty, and we don't have showers here. So to address both the fitness and sweat issues, I wore workout clothes to work today, and applied deodorant and changed when I got to the office. I felt much more presentable, and did the 2.3 mile walk in 42 minutes, when it would usually take closer to 50. This while carrying a fairly heavy backpack as I brought my camera in addition to the work clothes. And by actually getting out of bed when the alarm went off at 5:45 instead of lying there for another 1/2 hour like I usually do, I was at my desk and ready to work by 8 a.m.
I think I'll keep up this habit, which should be especially helpful once it starts raining; I can just strip off my soggy clothes and put on fresh ones. boyziggy has been wanting to leave the apartment by 7:10 when we walk partway together anyway, so this should work out well for both of us.
*A number of people are mystified when I express a desire to lose weight, as they tell me I "look great" or at least "don't look fat". I'm flattered, but I do think I should weigh a good deal less, independent of what the height-weight charts say (the currently accepted BMI range translates to about 114-140lbs for my height and gender). I don't believe this concern makes me guilty of being overly concerned about body image; I'm just recognizing that I have excess unnecessary fat that I can get rid of with enough self-discipline.
