פירוש על קידושין 65:15

The baraita had taught that the sage should not trouble the people to rise in front of him. Abaye adds that a sage will live longer by not making other people rise. It seems that there is some sort of “measure for measure” reward in this idea. Making people stand in order to honor oneself means using their energy, in a sense shortening their lives. Avoiding using other people for one’s own ends brings one longer life.
