Better medicine will lead to a polarization of the age structure of society: there will be more older people and more younger people. Gradually, as birth rates fall and contraception becomes widespread, a reverse pyramid will be formed: most people will be middle aged and old. This offers a clear view of professions which will be required in the future: Professionals to take care of older and younger people (which have very similar needs): nurses, paramedics, nannies, entertainers, leisure time professionals, companions, specialized equipment manufacturers, operators of homes for the very old or for the very young, pension planners, manufacturers of specialized medical and paramedical needs and products for both age groups, legal and accounting specialists in pension and inheritance laws and tax planning. Virtually every industry and field of human activity will have to adapt themselves to these demographic changes. Age-related expertise will develop in each one of them. This applies to the arts (mainly music and cinema) as well as to the crafts, to industry as well as to agriculture, to infrastructure as well as to government. Human society will be enormously influenced by these shifts.
