At 43-years-old, Jennifer Aniston looks better than ever (Jen actually credits yoga for her "hotness").But like many of us yogis, Jen gets upset when she can't practice yoga :(When asked about keeping in shape, Jen told Marie Claire Australia: "I think being happy and smiling and laughing a lot helps. I work out, I drink a lot of water. And yoga is still very important. I love it. If I don't do it then my spirit sort of goes." Do you also get upset when you can't practice yoga?
