Look, everything is going to be fine. I don't NEED to exercise. It's like lettuce on your burger. OPTIONAL.
But you are choosing to harm yourself!!!! You should at least go for a walk. You can come with me! Or you could stretch, then you don't even have to leave your room!
Tell me, Sasha, when has anyone needed to do the splits for daily life, huh? And why would I practice walking?! I'm not one year old!
