More old wives tales?

i think i need to include more old wives tales, as i only seem to have one in comparison to the other superstitions that i have.
The one that springs to mind is this idea of wet hair leading you to catch a cold, i know i always used to be told this as a child.
and while there is no medical link that it causes u to catch a cold, its still passed down as true.
Ive always been fasinated by the look and feel of wet hair, and how it looks, the shapes it forms and the pattern it creates so i think there is something that can be done here to show this superstition.
The thing i would need to experiment with would be the lighting, as it would be difficult to show the detailing with such a fine thing as dealing with hair.
