I am 63 and have had mixed results with the surveys. I have not had the disappointing experience where I spent over 15 minutes completing a survey only to receive 5 points. There have been many times that I have received between 20 and 50 points (however, I have received 5 points more often than the greater number of points). I have not felt cheated, and I understand that my demographics are often not those sought in most of the surveys.
