Welcome to the official YouTube channel of Tissa Jananayake, where science, life, curiosity and traditional knowledge come together. This channel goes beyond biology. Our goal is to make knowledge simple, interesting and meaningful for everyday life. We explore biology, the human body, health and wellbeing, the brain and human behaviour, nature, education, student life, parenting, everyday science, and many fascinating questions about the world around us. We also explore Sri Lanka’s indigenous knowledge systems, traditional wisdom, cultural practices and knowledge passed down through generations, while looking at how traditional understanding connects with modern knowledge and scientific thinking. Our aim is not simply to teach facts, but to encourage people to question, explore, understand and think differently. Subscribe and join us on a journey of discovery.
