Define "change". IMO if one does not change, according to all the new experiences one has, one is no more than a sheep or a cow that has no desire beyond eating.
I have "changed" more times than I can remember in my life, sometimes willingly, others because I had to. Such events as travel, marriage, illness all produce change in us regardless of our desire to not do so.
I have a neighbor that does nothing but sit in the sun smoking, or chatting occasionally. While I doubt he has my problems, I wouldn't swap places with him, even if I could. Us oldies can experience life more than just waiting for the end.
