Just some things of mention:
Coffee...yes, it is a food group in my professional opinion. :)
Chocolate...uh, coffee needs a good friend.
Music (prog rock, prog metal, hard rock, metal, classical, a capella)
Board (and card) games. A few of my favorites are Lords of Waterdeep, Terraforming Mars, Dominion, Splendor, Le Havre, Power Grid, Monikers
Hiking and very long walks with our dog, Macey.
Hanging out at coffee shops with a good book or friend.
Learning Italian. Currently, at an intermediate level.
Reading (fantasy fiction, select science topics, social reform and justice, philosophy, etc.)
Cajun cooking, grilling, Mexican food, and baking
Street tacos. Three words: mustard ancho sauce...'nuff said.
Thai food. It is delicious.
Falafel. Oh. How. Delicious.
Hiking. (Bring some falafel, beef jerky, nuts and chocolate. Whaaaat?)
Writing. (It keeps me thinking.)
Being artsy. (I like to draw, work with digital media and am learning how to make pottery.)
Mostly...spending time with my family, friends, and learning something new about science with my students.
