 There's bad stuff in the air, bad stuff in the water, bad stuff in the food. That's all stressful. There's exogenous toxins like dry cleaning fluid that gets into the body. That's a stress. There's emotional stress. There's financial stress. There's a stress of aging. Weather is a stress. Political stress, right? Political stress, that's a big one these days. So it's not really about the stress. It's about how strong is your body internally.
