Important Health Warning For Summer

I've got no idea why this is necessary, but I pass on this important health warning:

Doctors in Phuket, Thailand, are warning vegetarians at the annual Chinese Vegetarian Festival that piercing their faces with knives, axes, spades and beach umbrellas could expose them to health risks.

Especially the beach umbrellas.

I presume that piercing your navel with an axe might be OK.
