>Every once an a while I have this overwhelming sensation of smell. And I would say with much modesty I have a great sense of smell even when I'm smoking I can smell a lot. So now I have been with out smoke in my sinuses for a few days and the temperature and humidity and smell are overwhelming. I can almost put my finger on the memories that are welling up in my sizable nose. I have a great sense of nostalgia and I don't know why.
