6-2-1 rule

The 6-2-1 rule is a convention hygiene guideline. The rule mandates the following:


 * 6 hours of sleep per night.
 * 2 meals per day.
 * 1 shower per day.

These numbers are lower limits and not intended as upper limits. The third part of the rule is to prevent con funk - all parts help to avoid con crud and concurrent post-con depression.

History
The rule seems to have been devised by science fiction fandom. One story attributes its creation to Bob Passovoy, MD of the Dorsai Irregulars. The rule has been in use in the furry fandom since Confurence.

Parodies
At Anthrocon 2007, the Dorsai Irregulars proposed a new variation of this rule:
 * 6 miles walked per day.
 * 2 snacks per day.
 * 1 nap per day.
