actually the thread raises an interesting point. In the early 80's a test became available for those who might be at risk of Huntingdons disease. The disease is a terrible degenerative one as you gradually lose your physical functions with your mind being the last to go. There is no cure. The onset of the disease is not until early forties. In a NOVA documentary the test was offered to several people including Arlo Guthrie who declined to take the test. One lady who did take it was devastated to find out that she will get it. The advantage of having this test really is to test during the preganancy and then there is a choice to terminate the pregnancy... It is unlikely that Arlo Guthrie has the disease as it would have occurred by now. The question is if that test was available to his mother and she would have made the decision to abort there would have been no Woody or Arlo and their subsequent legacy. There are similar tests now for certain types of cancers (ie some people carry a gene which makes them more likely to get cancer). The movie GATTACCA (which admitedly I havent seen, but know a little about) raises those very same points although to an extreme. Im not sure if Id take the test Id rather not know, on the other hand its better to prepare ones family. What would other people choose if that test was available?
