Why Chinese said in Cantonese, "Tired like ham?" What's ham gonna do with tired? Well, finally I figured this century old meaning out. It might take one person in thousand years to solve this mystery and I did by myself. How does a ham feels like? Lazy by itself, and it only stays in a flat surface so when you are so tired, you would feel like a ham. Lying down like a ham and never feels like waking up. Mystery solved.
