Over half of the marriages in America end in divorce. Divorce is hellish. Getting remarried cannot help this.
Linda Waite of the University of Illinois-Chicago says: "Losing a marriage or becoming widowed or divorced is extremely stressful. It's financially, sometimes, ruinous. It's socially extremely difficult. What's interesting is if people have done this and remarried, we still see, in their health, the scars or marks -- the damage that was done by this event. Divorced people have more chronic conditions, more mobility limitations, rate their health as poorer than people like them in age, race, gender, education who've been married once and are still married."
