"We had an evaluation were recommended for about $14,000 worth of brain work. I bought Brain Safari for my 14 year-old son, my 15 year-old daughter and for myself ( age 55). I am nearly finished with the program. I cant say what it has done for the kids yet, but I know for myself, I have a much better degree of concentration and memory. I am looking forward to seeing improvement in my daughter's logic and my son's processing speed. My children enjoy the program and I have not had to remind them to do it. It cost us less than one hour of brain training. We all wish there were more logic problems in the program."
