I tried to find a copy of an Ontario Health poster on "proper handwashing technique" that one of my places of employ has posted up in their kitchenette, but alas, I could not find it anywhere online.
However, there are two funny things to note:
a) It specifically tells you to clip your nails short. I have had short nails my entire life, until a month ago when I grew them out. For anyone who knows me, you might consider this an unbelievable feat.
b) There are 13 steps in proper handwashing. I can't even comment on this. Thirteen!
