The importance of conquering cynicism for a healthier, happier life

According to Thomas Hobbes, one of history’s most famous cynics, life is “nasty, cruel, and short.” Jamil ZakiIronically, this is likely true if you are someone who has a cynical, Hobbesian view of life, who sees the worst in humanity and distrusts no one, according to John F. Kelly, director of the Stanford Institute for Social Neuroscience in California.

Zaki didn’t always think this way. He’s spent 20 years studying and lecturing about the brain circuits behind empathy and kindness, but all that time he’d harbored the dirty secret that he was a cynic. He began to examine his cynical perspective after the death of his friend Emile Bruneau, who studied the neuroscience of peace and conflict and was “one of the most hopeful people I’ve ever met,” Zaki says. He discovered that being a cynic is not only harmful to our lives, it causes us to believe things that aren’t true. Luckily, as he explores in his upcoming book, there are tools we can use to combat cynicism. Hope for Cynics: The Surprising Science of Human Goodness.

Alison Flood: What is cynicism?

Jamil Zaki: Cynicism is the theory that humanity in general is selfish, greedy and dishonest. Theories influence our behavior, what we do and don’t do. Cynics use their theories about people to guide their behavior in society. It changes how they see people, it changes how they interpret others, it changes their behavior, such as not trusting others.

What is the difference between cynicism and skepticism?

That’s really important….

Shaving your legs: a secret weapon for conquering the rush hour commute

Cyclists, from Team GB athletes to daily commuters, understand the importance of marginal gains. They constantly optimize their nutrition, equipment, and position to improve their race times by reducing drag.

It’s not surprising that some middle-aged men in Lycra (MAMILs) are considering shaving their legs. The idea is simple: removing leg hair can reduce drag, the force that slows down objects moving through the air. And on a bike, air resistance is the main factor that hinders speed.


When you’re cycling, the air in front of you moves as you move, creating wind resistance. To enhance aerodynamics, it’s crucial to optimize how the air flows around your body, reducing drag that holds you back. This is why cyclists wear skinsuits, position themselves low on the bike, and helmets are designed like sports cars.

There’s ongoing debate among riders and engineers about whether shaving your legs actually makes a significant difference in speed. An interesting study by a bicycle manufacturer tested shaved legs in a wind tunnel and found a 7 percent reduction in air resistance compared to natural legged riders.

In a 40 km time trial, this improvement could potentially give you a 79-second advantage over competitors. For professional riders, this could mean the difference between winning and losing.
