Judith Shulevitz

In an article for The New Republic, Judith Shulevitz writes that as people have increasingly waited until their 30s to become parents, there has been a rise in developmental and neurocognitive disorders. Moreover, she says that the age of both parents affects the health of the child.

Writer Judith Shulevitz started observing Shabbat because of her own ambivalence about the traditional weekly day of rest. Her own experiences with the ritual -- as well as its larger historical context -- are examined in her new book, The Sabbath World: Glimpses of a Different Order of Time.
