What are the advantages of climbing stairs instead of taking the elevator?

Take the stairs instead of the elevator. First, exercise. Climbing stairs after meals not only helps digestion, but also achieves the effect of long-term exercise. The second is to avoid the horror of sudden power failure. If there is a sudden power failure and the elevator doesn't run, you are not afraid to climb the stairs. However, taking the elevator saves time and effort, which is convenient and fast!
