Yeah but part of that is just sharing the same social space. It's pretty common for people to meet at work or at school and then start dating and eventually marry. For large portions of your life, especially in law and medicine, school dominates your life and virtually all your friends and potential mates come from that pool. Same for work or professional life. Have you ever hooked up with a coworker or classmate? Many people have. Doesn't matter the profession. It's less common for professions that are not as gender balanced, of course, but it still happens.
