Having lived in Arizona for almost two years, I should be keenly aware of how important proper hydration is. However, it’s easy to forget here in Europe where the climate is so much milder. Earlier this morning, I bought a 1.5-liter bottle of mineral water while waiting for a train. I was a little surprised that I was able to drink it in about ten minutes. Mostly I’ve been drinking coffee and beer the past couple weeks, and I’ve been sweating a lot as I walk around cities or haul my pack around train stations, so I was probably poorly hydrated. From here on, I’m going to make it a goal to drink three liters of water per day, or more if necessary. I’m just over two weeks into my trip, and it would be a lousy time to get sick.
