Not related to food at all...
When using a hedge trimmer to trim bushes down near knee level, do not let your mind wander! It can lead to things like stepping forward before you've moved the hedge trimmer, and that leads to visits to the UR. Not that I've ever done this or anything...

No, I don't have scars on my knee...what makes you say that?

Also, if someone tells you that lots of people are allergic to a certain type of plant, don't respond with "I'm not allergic to anything!" and proceed to pick up two armfuls of said plant trimmings. It's not an especially pleasant way to find out that yes, you are allergic to something. (the plants are poison sumac...should have guessed from the name, right? and dogwood)
