“Now,I'm no scientist,but I know what endorphins are. They're tiny little magical elves that swim through your blood stream and tell funny jokes to each other. When they reach your brain,you hear what they're saying and that boosts your health and happiness. "Knock Knock... Who's There?.. Little endorphin... Little endorphin who?... Little Endorphin Annie." And then the endorphins laugh and then you laugh. See? Its Science.”

“Near-death experiences release a lot of endorphins, resulting in a natural high," Tod whispered. "And it's totally true that one passion feeds another." "You know we're way past 'near-death', right?" "My endorphins aren't listening to you.”

“When your eyes are softly focused on the horizon for sustained periods, your brain releases endorphins. It's the same as a runner's high. These days, we spend our lives staring at screens twelve inches in front of us.”

“Remember laughing? Laughter enhances the blood flow to the body’s extremities and improves cardiovascular function. Laughter releases endorphins and other natural mood elevating and pain-killing chemicals, improves the transfer of oxygen and nutrients to internal organs. Laughter boosts the immune system and helps the body fight off disease, cancer cells as well as viral, bacterial and other infections. Being happy is the best cure of all diseases!”

“People with family histories of alcoholism tend to have lower levels of endorphins- the endogenous morphine that is responsible for many of our pleasure responses- than do people genetically disinclined to alcoholism. Alcohol will slightly raise the endorphin level of people without the genetic basis for alcoholism; it will dramatically raise the endorphin level of people with that genetic basis. Specialists spend a lot of time formulating exotic hypotheses to account for substance abuse. Most experts point out, strong motivations for avoiding drugs; but there are also strong motivations for taking them. People who claim not to understand why anyone would get addicted to drugs are usually people who haven't tried them or who are genetically fairly invulnerable to them.”

“Each happy chemical triggers a different good feeling. Dopamine produces the joy of finding what you seek– the “Eureka! I got it!” feeling. Endorphin produces the oblivion that masks pain– often called “euphoria.” Oxytocin produces the feeling of being safe with others– now called “bonding.” And serotonin produces the feeling of being respected by others–“pride.”
