maybe it's time to retire.  Not all seniors own homes.  those who do not are the most likely to have inadequate retirement savings and most at risk in relation to their fixed incomes.
.
in addition you've taken the term 'fixed income' much too literally.  The real issue for seniors is that they do not have the capacity to earn additional income if their investments are not adequate.  While their income may change from time to time ....if it does not meet basic needs they can not get a raise or a better job or more education.  they simply go without.

I don't think I'll recommend UNB for Econ to anyone I know.
