Dirt is good for you... Not gossip dirt. That stuff's totally toxic. But good, honest, from-the-soul-of-the-Earth DIRT is fantastic for you (I think). All those hand sanitizers, and "disinfecting" soaps do a great job at nuking bad bacteria, but they also have the same effect on good bacteria; the stuff that helps keep our immune systems strong and build up resistance to diseases, bugs, and other general heebie-jeebies.
Thanks for stopping by,
PS: I'm not sure who the guy is that originally spread the rumor that raised beds were weed-freed gardens, but he's a turd.
