<s>[INST] Dr. Smith has recently arrived at the hospital after an emergency call. He can choose the elevator or the stairs to get to the 18th floor. The stairs are not a pleasant option for Dr. Smith, as he has the flu and a runny nose. The elevator, on the other hand, is a preferable option but is currently out of order due to maintenance. However, there is an outrigger elevator that is available, but only goes to the 9th floor, and from there Dr. Smith would have to take the stairs to get to the 18th floor. Given this scenario, what are the two reasons why Dr. Smith would opt to use the outrigger elevator over the stairs in this scenario?[/INST]
