Is there any reason not to use olive oil as a moisturizer?

It’s so moisturizing. I use it all over my body and I put a tiny bit on my face combined with face lotion. I wake up feeling like a baby! There’s no chemicals in olive oil, am I right? If you don’t use too much, it’s not oily….no gross smell, it is surely not more expensive than a good lotion….so why do people stare at me when I lotion up with olive oil? It makes my skin look amazing too! People comment. I’m always amazed. So am I missing something here?!?!?!?!?!?!?!
