I loving love cooking, and I typically make a show out of it called "Cooking with McJob" (I'm trying to get equipment so I can film in a studio-style kitchen to make it a serious series). I used to do guitar, but I had to sell it off. Puzzles and LEGO keep my hands busy whenever I'm watching shows or listening to podcasts. Obviously, I do a lot of writing, including creative, research articles, technical documents, and I even get paid to do assessments for my friend. I'm also a moderator and/or community manager for several online groups.
I need to start doing more physical activities, though. My health is totally forgeted through lack of exercise and diet.
