The computer age and Internet have brought a valuable resource of information to retirees and seniors. The Internet is full of information on Social Security, prescription drug issues, Medicare programs, affordable housing issues and many other related concerns. There are websites that are just for retirees. If you do not have access to a computer or the Internet there are many places that will either teach you or let you have time on their computers.
Most local libraries are now able to offer Internet access.
Local senior centers and junior colleges also have computers available for use by the public.
