The hippocampus - a structure in the brain - controls the brain's ability to learn and form memories of day-to-day facts.

But research found that the activity in the hippocampus steadily declines with age. The memory of subjects in their 50s and 60s weakened as subjects recalled events that were up to 12 years old but reached a plateau during older remembrances.

A favourite of most people across the world, french fries come in many shapes and sizes and are loaded with additives to add that irresistible taste. A regular serving of fries has 500 calories, while the same serving of regular potatoes has about 150.

Getting the right nutrients in your body first thing in the morning is hugely beneficial when it comes to maintaining focus throughout the day.

Eating a wide variety of wholegrains, fruits, vegetables, nuts, seeds and legumes throughout the day ensures that blood sugar levels are stable and provides the brain with healthy fats, carbohydrates, protein, antioxidants, vitamins and minerals. These all work synergistically to promote brain health, focus, memory, concentration, and health in general.

Lack of sleep makes it worse. When you get less sleep than the recommended 7 to 8 hours a night, you begin to accrue a sleep debt.

When we want to maximize our physical health, we should not only focus on a balanced diet and exercise but also on our social relationships.
