According to a massive RunRepeat study based on over 34 million race results, the average running times are:

• 35 minutes for a 5K
• One hour and two minutes for a 10K
• Two hours and 14 minutes for a half-marathon
• Four hours and 26 minutes for a full marathon.

We should keep in mind that the data is collected from race results. It doesn't mean every runner is racing or running as fast as they can.

The human brain is a highly complex electrochemical organ, generating as much as 10 watts of electricity.

This electrical activity is displayed in the form of four types of brainwaves: Beta, Alpha, Theta and Delta which correspond with focus, rest, creativity and deep sleep.

We are always as young as we would ever be in the course of our lives.

Society is youth-obsessed and gives us constant signals that having grey hair, and showing other signs of ageing means our value has declined. But as we grow old, we become expansive and confident, as we understand the world better, can communicate more effectively and are wiser than in our teens.

We all seek happiness, and there is a scientific way we can find it.

Dopamine, the feel-good chemical in our brains, positively affects our mood, focus, energy and behaviour.

Chewing gum has been around for hundreds of years in the form of chicle, a resin obtained from the sapodilla tree in southern Mexico and Central America.

Long ago, the Mayans and the Aztecs knew that by cutting the bark, they could collect this resin and create a chewable substance from it. The Mayans cooked and dried it into "cha" to quench thirst and prevent hunger. The Aztecs used it as a breath freshener but viewed public gum chewing as unacceptable.

Sleep needs vary from person to person. Age, genetics, lifestyle, and environment all play a role.

According to the National Sleep Foundation, adults need 7-9 hours of sleep a night. People who sleep seven hours a night are healthier and live longer. While the guideline is helpful, you are the best person to judge how much sleep you need.

The key to a healthy smoothie is to get the right balance of vegetables, fruit, protein, and fat and embrace variety.

You can put almost anything into a smoothie, such as water, non-dairy milk or kefir, fruits, vegetables, seeds, nuts, protein powder, maca or matcha, and toppings such as coconut, granola, and cacao nibs.

• Researchers found the pandemic and resulting lockdowns caused people worldwide to change their health behaviours, cut back on physical activity and eat more comfort foods. Anxiety levels increased while sleep became disrupted.
• The researchers also found that most people became more sedentary and gave in to their food cravings, such as sugary snack foods. People classified as obese gained more weight and had the largest declines in physical activity.

Around 30 to 50 percent of people sleep between the hours of 11 pm and 7 am. Another 40 percents are either slightly morning people or slightly evening people.

To understand why some people are early birds while others are night owls, we have to take into consideration the body's circadian system.

This is a common misconception.

Also, waking up a few times per night is not necessarily a cause for concern. The most important thing is how you feel when you get up: refreshed, ready to take the day or confused and unable to function?
