Amazing what excercise can do

Today I was tired.  I couldn't keep my eyes open during one meeting (it didn't help that the lights were turned off for it!)  and I couldn't seem to get enough coffee.  Over lunch, I lugged myself to the Y.  I checked in, took a bio break, and mosied (sp?) on over to the elliptical machine.  12 minutes later, I was really into it - great music helped me keep up my momentum.  30 minutes later I was no longer tired, but sweaty and energized.  I think a mid-day work out is just what the doctor ordered to keep me going throughout the work day.  It also helps my weight loss efforts and wallet (since I am doing something other than shopping).
