When attending a convention, three things need to be done.
Survival for health:
5 Hours of Sleep
2 Meals
1 Shower
Why? A body needs sleep for functioning, especially in a chaotic environment. Meals prevent h-angry and low blood sugar. Showers are needed for the high-contact, close quarters. People are sharing your space. The showers are a kindness for them … and a health prevention benefit for you, reducing the amount of transmissions on you during your overnight sleep. (Shower before going to bed!)
