One constant sickness

everday someone gets sick. it's a constant here. no one can pinpoint what causes it, except Wright, who swears that since he stopped brushing his teeth with tap water, he's felt fine. a couple of us have been wondering whether we're going to have upset stomachs and the like from now until we leave. even when the sickness isn't bad, being sick wears on you, especially when you're trying to tour & enjoy a new country. let's hope we figure this out soon so we can enjoy the next 5 weeks
