Relationships :- I suppose they are affected / effected by surroundings, enviroment / s, finances, Education, experience/s, housing etc, etc. In the past :- larger families, closer proximity, difficulties to live with such as overcrowding etc. Possibly people shared tasks, had similar experiences, delegated tasks etc.
Whereas "nuclear family", long working hours, taking work home, commuting, living distance from other family members etc. Seems more isolating, less social etc. Some have become self - centred, materialistic etc. Yet it seems that relationships, socialising etc is important to mankind. Yet many workplaces may have little or no access to a work canteen ( parliament has High Class Restaurant Discounted via British Taxpayers Contributions). :- "Them and Us".
Parents are keen / eager to Bond with their children. Babies and children are valued in our Society. Individuals / People seem to need to be Valued and Respected irrespective of their age etc. Maybe that attitude / culture could "Improve the Health of the Nation".
