This is the bi-weekly visible open thread. There are hidden threads every few days here. Post about anything you want, ask random questions, whatever. Also:

1. Comment of the week is Andy McKenzie on what eunuch studies tell us about testosterone and lifespan.

2. A public reminder: me linking to a website doesn’t imply that I endorse every single thing on that website, or every single thing the author of that website has ever said. I mean, it doesn’t even imply that I endorse the specific thing that I’m linking to beyond finding it interesting in some way. But to whatever small degree it implies that I’m endorsing the specific thing I’m linking to, it doesn’t imply that I support the rest of the website even that much. Please do not request that I put an “I do not support everything at this linked webpage” disclaimer on specific links. I worry that it would imply I do support everything at linked webpages I don’t attach this disclaimer to.
