The instructor's rules were simple. Breathe through your mouth, not your nose; else the mask will fog up. Easier said than done; I got it wrong many a time. But once you fought habit and got the hang of it, the panoramic underwater world revealed itself to you with high-definition clarity.

Led by him, I slowly peered through the mask into what till then was crystal-clear water, shimmering in the sunlight. I saw pebbles, sand and my fluid shadow. I was in Nemo's universe. Sea cucumbers, sea anemone, clown fish, star fish, sea horses, parrot fish, butterfly fish and a bevy of colourful salt water fish swam past. A shoal of canary-yellow fish did a merry dance and another with vibrant blue fish followed it. They were oblivious to the snorkelers who struggled to take in the sight of a world so beautiful, so colourful, and resist opening their mouth wide in amazement; the tube would fall off!

Prebiotics are the lesser-known gut-health promoters which serve as food for good bacteria inside the gut. "We found that dietary prebiotics can improve non-REM (random eye movement) sleep, as well as REM sleep after a stressful event," said Robert Thompson, a PhD researcher at University of Colorado Boulder in the U.S. Prebiotics are dietary fibres found naturally in foods like artichokes, raw garlic, leeks and onions.

When beneficial bacteria digest prebiotic fibre, they not only multiply, improving overall gut health, but they also release metabolic by-products. Researchers fed three-week-old male rats a diet of either standard chow or chow that included prebiotics. They then monitored the rats' body temperature, gut bacteria and sleep-wake cycles — using electroencephalogram (EEG), or brain activity testing over time. Findings revealed that the rats on the prebiotic diet spent more time in non-rapid-eye-movement (NREM) sleep, which is restful and restorative, than those on the non-prebiotic diet.

How are metabolic by-products released?

In mid-2012 I completed my first massive online open course, or MOOC, the kind widely offered by Coursera, EdX, Udacity and so on in partnership with different educational institutions. It was on clinical trials and ethical practices, offered by Johns Hopkins, on Coursera. This was shortly before the MOOC sensation hit India, and when Coursera, which was founded by two Stanford professors, itself was just a few months old. The MOOC bug had bit me. The course I’d completed was mainly designed for health care professionals who would be involved in actual clinical trials, not college students who had no prior knowledge of that area. I decided to enroll in the course because it was the only biology related course open at the time. However, I did see hope in that sometime in the future I’d be able to get a glimpse of what classes are like in the hallowed halls of major educational institutions around the world. By early 2013, Coursera and EdX had partnered with so many educational institutions and expanded their course offerings to include everything from food and nutrition to Greek mythology to business, that I was spoilt for choice. I spent hours going through course catalogues and poring over course descriptions, almost delirious with excitement at the fact that I was actually going to be able to take classes offered by universities I had only dreamt of attending.
