I wonder how many of us think about what science may be able to do in the coming centuries, positive advances that might seriously change our lives. We all have some ideas about negative "advances," but it would be interesting to hear from PC'ers about the kind of positive advances we can look forward to.

My first candidate is the possibility that through some new form of imaging or blood test, the medical people of the future should be able to measure objectively the level of physical and/or psychological pain that a particular individual suffers from.

What about you? Take care!
