Being a biologist takes a dedication to a particular subject. Many biologists, depending on their choice of field, spend most of their lives studying one thing. Aside from dedication and years of schooling, being a biologist requires some flexibility in life. While it is very possible to work a normal 40 hour work week, it is also common to have to frequently work more than 40 hours. Those involved in the nature fields (zoology, botany, ecology) have to be prepared to spend days, weeks or months living in primitive conditions in order to gather the research required to complete their study.
