Your genes have been the new oracle. It tells you what to eat. The report promises revealing secrets. Eat more kale, less rice. Take methylated folate. Avoid coffee after noon. What is nutrigenomics? The notion that your DNA can guide your nutrition. Let us use one example to illustrate this.
Your body is always talking. The conversation may not be something you comprehend using words. Instead, the conversation uses chemicals, signals and electricity. It is taking place inside your body. One such signal is called the sympathetic tone. Think of it as your internal throttle. It’s part of your
CrossFit is a high-intensity training protocol. It combines multiple exercise modalities, metabolic conditioning, gymnastics, and weightlifting. So is CrossFit training apt for you?

There is a lens inside your eye. It sits just behind the coloured part, the iris. Its job is to focus light onto the retina. When you are young, the lens is clear. Light passes through easily. You see the world in full colour, in full clarity. But with time,
Your knees contain a remarkable fluid called synovial fluid. It acts like oil in an engine to lubricate your joints. It also delivers nutrients to the cartilage and removes waste. If you have knee pain, listen in. As we age, this fluid declines. Sometimes, it becomes thinner. Sometimes, it becomes

We like to believe the world is real. That it exists outside of us. That matter behaves in predictable ways. That consciousness lives inside the brain, watching it all unfold. But quantum physics shatters this idea. In the famous double-slit experiment, a particle passes through two slits. Until someone observes
Humans are unlike any other species on the planet. We possess a remarkable ability. We can learn by learning. Cognitive learning is not just about absorbing facts.

Dopamine loading happens when we flood our brain with stimulation early in the day. The most common sources are phones, sugary foods and mindless scrolling. These may
Each morning, as we wake up and go about our lives, we like to believe that we have free will. The ability to act purposefully driven by our mind. But science suggests otherwise. In the 1980s, neuroscientist Benjamin Libet conducted a now-famous experiment. He asked participants to move their wrists
