A true friend doesn't have guts; they beat you up and later plead with you to beat them back.
Let food be thy your medicine
The gut is the seat of all feeling. Polluting the gut not only cripples your immune system, but also destroys your sense of empathy, the ability to identify with other humans. Bad bacteria in the gut creates neurological issues. Autism can be cured by detoxifying the bellies of young children. People who think that feelings come from the heart are wrong. The gut is where you feel the loss of a loved one first. It's where you feel pain and a heavy bulk of your emotions. It's the central base of your entire immune system. If your gut is loaded with negative bacteria, it affects your mind. Your heart is the seat of your conscience. If your mind is corrupted, it affects your conscience. The heart is the Sun. The gut is the Moon. The pineal gland is Neptune, and your brain and nervous system (5 senses) are Mercury. What affects the moon or sun affects the entire universe within. So, if you poison the gut, it affects your entire nervous system, your sense of reasoning, and your senses.
From the gut comes the strut, and where hunger reigns, strength abstains.
I'm going to gut you like a fish.
I've never gone wrong trusting my gut.
I just followed my gut feeling when I went to Hyderabad in 2008.
I go by my gut feeling.
I am someone that relies on my gut feeling.
