The aging of America has created unprecedented opportunities for professionals who work in the senior market.   At some point in the lives of our aging parents things slip out of control.  It may be a subtle change over time that finally becomes unmanageable or the sudden arrival of a medical setback. As much as we want them to remain independent, events take them off course and tough decisions need to be made about the quality of their lives.   A friend of mine got a call late one night that his elderly father has suffered a heart attack and was in the hospital. He caught the next plane and flew to be with his parents. But when he arrived at the hospital, he got more than he bargained for: his sister told him that his mother was suffering from early memory loss, something his parents had carefully kept a secret from the rest of the family. Now the life-long independence his parents treasured so much in their late seventies was turned upside down. It was time for the children to swing into action. It turned out to be a disaster.
