Crawford is talking about castoreum, a naturally occurring anal secretion found in beavers. The furry animals use it to mark their territory. We humans, however, have also found uses for castoreum. Most notably, as an ingredient in vanilla-flavored and vanilla-scented products.

I’ve never really felt the need to purchase a smartwatch because a lot of them aren’t very functional, but at just shy of $30, the Martian Notifier Smartwatch was worth checking out. For that low of a price, it actually does feature an impressive amount of functionality, and comes in handy when you don’t want to be carrying around your […]
