Probelms With Probelms Where is the Help?

I was told a long time ago that once you have discovered the solution then there is no more a problem. Well, I have seen many solutions come and go yet some people still maintain the same problem. I have seen so many commercials giving answers to weight problems, relationships and countless of other problems most people have in this world, the question was answered many times yet the same question is asked yet again. What can you tell a person who just doesn't caught on. Is it a mental illness in the world today?
