Good grief...I will have to print this article out for my husband...he also thinks like this and has for a long time...he is just an average guy, no scientific training of any sort...but he has always believed that the human body, is like a car, and that it can always be fixed...he does believe that we should be able to live at least a couple of hundred years, and in relatively good health...
Yes, I am married to and live with a whacko....he has a lot of odd beliefs...its never dull around here, thats for sure...
Your husband is quite right IMHO. I've always said the generation is coming that will live forever, or certainly for several hundred years. I also always say we (my contemporaries) will miss the boat. Also, unlike the folks who say they would be bored, etc, I would have no problem being "bored" for 500 or 500,000 years given the opportunity.
