Years ago, when I was at my healthiest and everything physically was going really well, I figured out the secret to life: “Eat right, sleep right, and exercise.” This is exactly what you said!
Everyone has a choice, free will. Yes it's hard to find the truth when it's purposefully hidden and surpressed but individuals have a duty of care to themselves and those they love to seek out alternative remedies that deal with the cause not just the symptoms.
My body is usually warm, to hot and my foot is always tingling hot. Does that means I have abundance of yang chi? Take note, I am a meditative chi gong practitioner the last years.
