Missionary Longevity

GOLDEN RULE of missionary survival as quoted from a veteran on the field when I found this in my meal:

"Brand new missionary on the field for less than 6 months:  so grossed out you immediately stop eating."

"Missionary with 6 months--1 year field experience:  remove bug and continue eating."

"Missionary with more than 1 year field experience:  bug is a protein bonus and...naturally...comes with the meal."
