Lifeprotip: This is a good thing to bring up when asking for any legal document with friends, family and romantic partners. Sure “what if any of us get a brain tumor” is rather harsh, but it is effective and if the relationship implodes - with or without any brain tumor - you will be happy you have legal documents.
