The physical act of being a lawyer isn’t all that dangerous. You will not be cliff diving or jumping out of a helicopter in the course of your work. There is a lot of reading, staring a computer, going through legal documents, sitting, and reading. Did we mention reading? You will be doing a lot of reading. So you really face the same physical dangers that anyone who works in an office faces: eye strain, muscle strain, and paper shredder accidents.
Depending on who your clients are, however, you may face some serious physical danger… especially when someone you put behind bars gets out on parole. Or has an angry brother. And if you’re a lawyer for the mafia… fuhgedaboutit. Keep your friends close and your enemies closer. And make sure you can see out of all your windows at the same time.
