They are generally not aggressive

The human brain is the where the aggressive emotion originates, and is often caused by outside stimuli. Although agression has been proved to increase testosterone production, it also has a negative effect on blood pressure. Constantly high levels of blood pressure can result in serious cardiac problems, mental stress, and higher rate of sickness.

They eat fairly simple foods

Some of the world's oldest people have been of Italian heritage, and a great reason to attribute to their longevity is their basic meals. By keeping to a select range of ingredients which are high in anti-oxidants, vitamins and minerals the human body will continue to absorb the nutrients it needs.

A balanced diet of meat and vegetables

A healthy combination of fruit, vegetables and meats will ensure your diet has sufficient energy input. Red meat is expecially good for you as it contains anti-oxidants, and vegetables contain anti-oxidants.

Eat breakfast on a regular basis

Breakfast has been proved to be the most important meal of the day. The nutrients from this meal is the first injection of energy after a 10 hour period (from dinner). It is breakfast which keeps your energy levels up and allows you to wake up easier than if you had not eaten breakfast.

Exercise fairly regularly

A regular exercise regime will help maintain your muscle development, and help to stave off bone & muscle deficioncies. Some of the effects of lack of exercise include obescity, muscle strain, and bone density thinning.

They do not eat to excess

Studies have shown that people who eat large meals which exceed their necessary intake have a greater chance of becoming obese. Generally speaking smaller meals rich in meats and vegetables leave you feeling fulfilled. And if you do happen to still be hungry, a small tub yoghurt will stem your hunger.

Many are not alcoholics, and not many are teetotallers

Many studies have shown that heavy drinkers will cut severe amounts of their life from their life expectancy from heavy drinking. Excessive alcohol consumption damages your kidneys, and causes the brain to retard synaptic signals.
However it should be noted that studies have also shown, a glass of red wine a day after meals help to boost anti-oxidant levels in the blood. Thus helping circulation and reducing the risk to blood clots.

Genetic history of long life

The world's oldest documented person was born in France, and it should be said that Jeanne Louise Calment was very active right up until her 122nd birthday. She even took up fencing at 85, was riding a bicycle at 100. Her father lived until the age of 93, her brother 97, and her mother 86.
Although she did outlive all of her nearest relatives her case was exceptional even though it was supported with her genetic history.

They generally follow a routine in their life

Routine can be anything from regular exercise, to regular studying, walking, or even visiting a zoo. It is routine which trains the human mind into a rythum, and with the brain's rythum comes the body's rythum. If your body and your mind are in perfect synch you can expect to feel great, and be quick minded.

They have a sense of meaning in their life

A sense of meaning is 'the' most important aspect of life longevity, without this sense you and your body will have no drive to compell itself to exercise, learn or even develop. An example of people with little meaning in their life would be excessive drinkers who have developed a physological rutt in their lifestyle.

It should also be mentioned that a great sense of humour will also help you to keep your sense of meaning. As has been the popular saying, "Laughter is the best medicine".
