Physical pain/illness

Hi Brooke,
Your 50/50 positive/negative emotion theory has been so helpful to me! I’m wondering if it also applies to physical symptoms. That believing we are entitled to a body with no physical pain is also unhelpful? I notice that when I have heartburn or an awful cold or migraine that my brain thinks it’s all gone wrong. But maybe expecting physical pain or discomfort would be as helpful as expecting 50% negative emotion daily?
