Warnings

I have been subscribing to New Scientist for a few years. They have a section called Feedback, not to collect feedback from readers but documenting funny (mostly stupid) things readers report. Here are a couple of recent examples:

MEGAN, a border collie belonging to a colleague of Gerald Legge, was recently taken to the local vet because she was suffering from skin irritation, Legge tells us. To help calm her agitated response to the condition, the vet prescribed some Tavegil antihistamine tablets. The medicine came with the instructions:
"Take two tablets as a single dose. Give in the evening. FOR ANIMAL USE ONLY. May cause drowsiness: if so do not operate machinery or drive. Avoid alcohol."

The instructions supplied with Bryan Carter's Sonic Plakaway toothbrush include a warning:
"Never use while sleeping"
