Nearly half of women over 50 say they sometimes leak urine, according to a new national poll. Of more than 1,000 women between the ages of 50 and 80 who answered the poll, 43 percent of women in their 50s and early 60s said they had had experienced urinary incontinence, as had 51 percent of those age 65 and over. Yet two-thirds of these women hadn't talked to a doctor about the issue.
