Every day more than 5,500 Americans turn 65, officially becoming senior citizens.  70% rank their health as "good," and only 4% live in nursing homes.  Dwelling in the murky middle ground are 23% who report problems with self-care, and 28% who have trouble with complex functions such as housekeeping.  Where is your parent in this range of self-sufficiency to needing some help to requiring constant oversight?  In searching for this site, you're already asking questions.

You are your parent's advocate.  If your parent sees several different specialists, you are the one person who can look at the whole picture and stand up for a parent who meekly accepts everything prescribed. Be informed and educate yourself.  Get a grip on caring for your aging parents!
