Why does cheese make me so happy

Why does cheese make me so happy? When I go to the grocery store, I immediately go to the cheese section. I love touching and looking at cheese, the textures, colors, and shapes amaze me and make me so happy. Why does this happen? Why does cheese give me this jolt of excitement and happiness?

(By the way, this happiness comes to me when I touch/look at cheese, not when I consume it.)
