Formal proof: 1) No physical object can have negative mass. 2) I am a part of the universe and have positive mass. 3) I am not Kenneth. 4) The sum of my mass and Kenneth's mass must exceed Kenneth's mass alone. Unless someone wants to dispute 1 or 2, we can be logically certain. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
