Another road map to the highways, detours and accident-causing hazards of marriage. A psychiatrist (and host of NBC's Talknet radio show), Ruben charts the usual problems that have produced a 50% divorce rate in the US. These include interfering in-laws, adjustments when children arrive, money and budgetary squabbles, sexual problems, the dual-career family and coping with retirement, aging and illness. His advice usually boils down to communication about and negotiation of difficulties. His case histories are fairly comprehensive and, like modern marriage, are resolved sometimes only by divorce. There's precious little about so-called supermarriages, which seem to be those that have successfully survived the various stages of wedlock. Ruben estimates that supermarriages are enjoyed by only 10% of couples, and rates his wife and himself as one of the lucky ones. Standard fare; probably useful for some readers with troubled marriages.
