Aging is hard on the rebellious

My mom was never very good at acceptance. She would always start by saying no. Getting old, however, is not something you can refuse forever. And in old age, the peaceful, submissive, fatalistic kind of women (and men, but mostly women) fare much better than the rebellious kind. She was never good at accepting her defeats, and she sees aging as a defeat. Does it have to be so? Can’t you see it as a process, with some physical limitations, but also some improvements ? Moral betterment maybe ? Working on what to transmit, and transmitting it ?
