Warming-up is overrated

Is is the little things in life that we take for granted. I am having the unique problem of being incapable of warming up before I practice. I never thought I would be admitting this, but there is something good about Temple's practice rooms. Minuscule, dark, and decrepit though they be, they have a balanced temperature (we will ignore the fact that they only have one temperature- hot). Since this week is spring break, I am trying to adapt to playing at home again. However, in a non-insulated, 300-year-old house one might expect drafts. The blustery weather this week as taken this tendency and magnified it ten-fold to the point where there is a continuous draft in the upstairs "conservatory." I have retreated to the third floor, but this has not improved matters much. I am still having trouble getting past the warming-up stage. I practiced for 40 minutes this morning and my instrument still felt cold- this must be good practice for something, but I don't know quite what.
