BEWARE THE DESERT APHRODISIAC

It's probably not a good idea to buy milk from a stranger:

Six men who were out camping in the desert near Al-Qaryat consumed large quantities of fresh milk from a shepherd who told them that it would give them energy and serve as an aphrodisiac... The six men were quickly rushed to hospital and admitted to the emergency ward as they began to vomit and suffer from diarrhea.

The milk was probably hot.
