25. For the purposes of section 23 of the Act, a person at home may be considered incapable of attending to one or more of the usual occupations of such a person if the physical or mental activity of that person at home, taking into account his or her age, is no longer sufficient to enable him or her to carry out, as he or she normally would, one or more of the household chores, care for his or her children or for any other member of his or her household, prepare meals and attend to clothing, provided the said person at home was responsible for that work before the accident.
