A problem only exists if you percieve it to actually be a problem. I'm an optimist, so I tend to accept most things and try to gain something good from them. I think we're now in a world where we're looking for problems, everythings under a microscope these days, take illnesses for example: nowadays, because we are continuously doing lab experiments on blood samples and the like, we are making ourselves more aware of the possibilities of illness and disease, in turn we are manifesting our fears, thus "proving" there's something to worry about. So you see, we are creating the problems, but also at the same time we are coming up with solutions to the problems too-in this case cures.
Personally, I think ignorance is bliss, and I believe what you don't know won't hurt you!!
