Men want their wives to take care of their bodily waste if they become bedridden or are left in other conditions requiring this kind of care, while women would rather be looked after by professional helpers or their daughters, according to a survey by Unicharm Corp., Japan's biggest maker of adult diapers.

Two-thirds of male respondents chose their wives as their preferred caretaker to change their diapers, while only 21 percent of the women selected their husbands.

Daughters were chosen by only 3.7 percent of the men but by 25.1 percent of the women. Professional caretakers were preferred by 26 percent of the men and 46.9 percent of the women.
