I write software which analyzes DNA. It's pretty interesting to hear the varied responses from lab staff when questions are asked. Many times, however, questions (or sometimes answers) end up being overridden by business needs (aka deadlines). Being a business, that's rather expected to happen now and then.

But it bothers me that many of the questions that end up being unanswered are typically some of the more fundamental questions I ask.
