hermetic (adj.): airtight (in a physical or metaphorical sense)
“Do we really want to travel in hermetically sealed popemobiles through the rural provinces of France, Mexico and the Far East, eating only in Hard Rock Cafes and McDonalds? Or do we want to eat without fear, tearing into the local stew, the humble taqueria’s mystery meat, the sincerely offered gift of a lightly grilled fish head? I know what I want. I want it all. I want to try everything once.”
― Anthony Bourdain, Kitchen Confidential: Adventures in the Culinary Underbelly
Sounds like: hermit tick
One day, I’m going to tick “live as a hermit for a month” off my bucket list. I’m going to live a hermetic life in the woods - I won’t touch any tvs, radios, computers or phones.
