Would anyone have believed you if you had told them we would be doing that? I'd argue that the lives of Americans have changed radically in the last 50 years. The problem is, as with fish not noticing water, it is difficult for most people to notice changes when they're marching along with them. I regularly attend a seminar by video conference these days. The way I do this is that one of the participants in the seminar gets out their laptop and video chats me over the wireless in the conference room the seminar meets in. I'm generally in another city, also on a laptop connected by wireless. People send me copies of the slides via the net at the last moment so I can follow along. This is all done with equipment that is not merely ordinary but actually cheap. Think nothing has changed in medicine? A couple of years ago, I had a set of symptoms that lead my doctor to worry about the blood flow in my brain. I went to a lab, got an MRI done of my head, and went away on my business. In 1960, the amount of unpleasant radiological equipment, including contrast agents, that would have been needed to do this would have made it essentially impossible. Today it is actually cheap and simple. My ophthalmologist routinely checks the surface topography of my eye using a computerized optical instrument that would have been impossible to contemplate in 1960. The deaths in Iraq among soldiers would have been as high or higher than in Vietnam were it not for astonishing improvements in trauma medicine that have saved something like 90% of the people who would have otherwise died 40 years ago. 90% is astonishing. We can even reattach severed limbs. Lets not even discuss the radical transformation of transplants, which were very difficult and generally resulted in organ rejection before the development of appropriate drugs -- they now happen orders of magnitude more often. I could go on and on. People just have no sense of how much everything has changed. -- Perry E. Metzger Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=32963
