YouTube video: Protecting and Maintaining Your Heterosexual House of Cards. A short and hilarious "documentary" which explains, among other things, while apparently-straight young men Do Not Make Eye Contact with each other. Linked by rosefox.
Advance Directives/Mad Maps/Plans For Not Getting Too Crazy. Advance directives are "official"-type documents that you give to a doctor while sane and healthy to tell them how you'd like to be treated when insane and unhealthy. Mad maps are more informal documents agreed between you and your friends/support people. Quite an interesting idea, especially from the point of view of preventing yourself getting too bad by having your own checklist of symptoms relevant-to-you. There's some really good stuff on page 2 with a bunch of headings that can be used. Anyway, random linkage in case it's useful for anyone.
