Weight Loss?

Judging by the way my clothes are hanging on me, I think I've lost 5-8 pounds over the past few weeks. I'm positive much of the loss can be attributed to the bone and muscle-jarring matatu and piki (motorbike) rides between Kisumu and Kegoye Primary School. It's an 18-mile trip that takes about an hour. Segments of the roads have been under construction for the past few years.

Hmmmm - Shouldn't the quantities of dirt and dust I inhale through the open matatu windows make up for some of that loss?
