Your family is planning a ski trip to a resort that is at about 10,000 feet of elevation. You suggest that you spend the first two nights of the trip at a hotel where the elevation is about 6,500 feet. When your children protest that they are in good shape and want to go immediately to the resort, you explain that you are concerned about altitude sickness and:
A) “Physical fitness does not necessarily prevent altitude sickness.”
B) “Just because you children are fit and don’t need the gradual change doesn’t mean your mom and I don’t need it.”
C) “Your mom and I will exercise more before the trip so that maybe we can reduce the delay to one night.”
D) “I’ll see if I can get some medication so that we don’t need to stop over at the lower elevation.”
