Why Dog Owners Live Longer - "dogs could be called wonder drugs"

Dogs are the most diverse mammal species on the planet (http://buff.ly/1pxxt0k). They can vary in weight from 6 lb (3kg) to 200 lb (90kg) when fully grown and have widely differing body shapes and hair types.

Dogs could be called wonder drugs

People who have dogs as pets are much less likely to have a heart attack. If they do have a heart attack, they are 2-3 times more likely to survive it.

Over more than 100,000 years dogs have evolved to recognize human emotions. It has been a collaborative process all along. Humans are able to recognize 6 types of dog barks expressing emotions and "intentions" such as fear, excitement, aggression and so on. Dogs are the only animals that specifically look at the right side of the human face where emotions are expressed.

Dogs follow directions while chimpanzees, the apes evolutionary closest to humans, do not. The smartest dog can learn 300 different words which is the vocabulary size of a 2-year-old child.

The "400 mnemonic":

400 million dogs worldwide
400 breeds of dogs have been developed by humans

According to a Cleveland Clinic psychologist, "dogs could be called wonder drugs":

Sexual life expectancy is longer for men than women

A BMJ study of middle aged and older adults showed that men were more likely than women to be sexually active, report a good quality sex life, and be interested in sex.

These gender differences increased with age and were greatest among the 75 to 85 year old group: 38.9% of men compared with 16.8% of women were sexually active, 70.8% versus 50.9% of those who were sexually active had a good quality sex life, and 41.2% versus 11.4% were interested in sex.

People in very good or excellent health were 1.5 to 1.8 times more likely to report an interest in sex than those in poorer health. At age 30, sexually active life expectancy was 34.7 years for men and 30.7 years for women compared with 14.9 to 15.3 years for men and 10.6 years for women at age 55.

At age 55, men in very good or excellent health on average gained 5-7 years of sexually active life compared with their peers in poor or fair health. Women in very good or excellent health gained 3-6 years compared with women in poor or fair health.

Physicians as a group are leaner, fitter and live longer than average Americans

From the WSJ:

Physicians as a group are leaner, fitter and live longer than average Americans. Male physicians keep their cholesterol and blood pressure lower.

However, doctors are less likely to have their own primary care physician—and more apt to abuse prescription drugs.

Lifestyle habits

Exercise: Many physicians say they "embed" it into their lives, making it a non-negotiable part of their daily routine, often early in the morning before demands pile on. One doctor says he gets up at 4:45 a.m. virtually every morning to train for marathons he runs. "But by 8:30 at night, I have the IQ of a zucchini," he says.

Smoking: Only 2% to 4% of physicians smoke cigarettes, compared to roughly 24% of the U.S. population.

Stress: For all their good habits, it's no secret that doctors are under enormous pressure.

Do Athletes Live Longer?

Short answers:

- bob sledders live 1.6 years longer
- ice hockey players live 4 years longer
- speed skaters live 5.6 years longer

This is only if you keep up your fitness level for your whole life (not an easy task).

Olympic medalists live an average of 2.8 years longer than their age-matched peers. More specifically, 8 percent more of the medalists than the non-Olympians were still living 30 years after they had won their medals.
