As I hit the reply key I realized that this link is quite old and so is likely no longer followed by the original posters. I did have a couple of thoughts though which I'll chance might (OK, probaby not!) be of interest to the occasional individual who happens this way.
I decided to go through medschool a couple of years after graduating with a degree in music. I'll admit that there were some sections of biology that were quite dull and seemingly quite irrelevant. But, if you'll excuse the cliche, there's something to be said about knowledge for knowledge's sake.
It's entirely reasonable for a person to have no burning desire for a deeper understanding of phloem movement needed to provide nutrients to vegetative matter... yet at the same time, I think that the more we learn about life and its workings (much like studying history) regardless of our personal take on its immediate relevance, the more it prepares us to develop our own opinions and philosophies on why we are here and what we want to do with our lives. I guess that's just a (excessively

) wordy way of saying that there's something really special about being educated on a wide range of topics.
There are no easy answers of course, but I think, the more aware one is of the varied nature of biology, philosophy and (my own bias), art, the more we are equipped to understand what has cme before us and maybe help prepare us for responding appropriately to everything around us.

... oh well, I imagine this post will never be read--which is probably a good thing. Too many thoughts are simply rattling around in there and I
really need to get back to studying..... g'night all....
