Vitamin D deficiency is common, and so is erectile dysfunction. Because both are widespread, researchers have spent years asking whether one actually causes the other. The short answer: low vitamin D is linked to erectile dysfunction in many studies, but a link is not the same as a cause. No major trial has shown that … Read more
Yes, corn digests in your body — but not all of it, and not in the way most people assume. Your small intestine breaks down the soft, starchy inside of a corn kernel and absorbs it as glucose.

When a person feels small, threatened, or unsure of their place in a group, pointing out someone else’s flaws can create a temporary feeling of superiority.
