A lot of our ideas about what we can do at different ages and what age means are so arbitrary — as arbitrary as sexual stereotypes. I think that the young-old polarization and the male-female polarization are perhaps the two leading stereotypes that imprison people. The values associated with youth and with masculinity are considered to be the human norms, and anything else is taken to be at least less worthwhile or inferior. Old people have a terrific sense of inferiority. They’re embarrassed to be old. What you can do when you’re young and what you can do when you’re old is as arbitrary and without much basis as what you can do if you’re a woman or what you can do if you’re a man.
