  1. The first time I learned this it was a huge relief for me. A fungus growing on your skin is gross, but its much less disturbing than my previous understanding, which was that a worm was tunneling through your insides and making weird sores on the surface at each end of the tunnel.

  2. Good article in CBC yesterday about a toddler who ate raccoon scat and had to be administered a rare drug to stop irreparable damage or death from ringworm. That particular type of ringworm isn’t a fungus, they’re parasites that consume tissue and essentially “eat you from the inside out”.
