In our first two weeks here, we napped twice a day! The altitude (8500′ at our house) was hard on our bodies. Then we went down to one nap per day, then every other day. Now we don’t nap much unless we really exert ourselves. Gary bought a great quality bike from a guy who was heading back to the US. It’s a hybrid road-offroad bike, so he can take it anywhere. When he rides it way down the mountain along the river trail, and then back up the mountain to our house, its nap time. I’m impressed that his lungs are able to manage the altitude and the uphill exertion! I still get winded when I walk up the steep terraced hillside from our veggie garden to the house. Progress: I can now walk from the bus stop up the unbelievably steep curving sidewalk through our hilltop neighborhood, often without resting. I love seeing that improvement.
