Hey there, folks! The name's Cassius, your friendly neighborhood nutritionist. I hail from the beautiful city of Seattle in the United States. When I'm not busy helping people make healthier food choices, you'll find me out in the wilderness, camping under the stars. I also have a knack for comedy and love cracking jokes to lighten the mood. Oh, and did I mention my obsession with radio-controlled model playing? It's my little escape from the real world. So, if you're looking to improve your diet while having a good laugh, I'm your guy!
