Bubble gum

Did anyone ever notice when they chew a piece of gum for the first few seconds it tastes like a bunch of stuff that attracts you? It's like Amortentia love potion that Hermione names in Slughorn's classroom. If you don't watch Harry Potter you probably have no clue what I'm talking about. Anyways, whenever I put a piece of gum in my mouth it taste like vanilla, coffee, and Irish potatoes. I enjoy all those things alot so I guess it makes sense. I wonder why that happens and if I'm the only person it happens to? Maybe I'm imagining it, but I'm okay with it.
