What actually happens to your body when you lift, run, walk or change how you eat, especially after 50? Each video follows one habit for a full year and shows what the research says changes inside you: your muscles, heart, bones, blood sugar and brain.

Hand-drawn explainers built on real studies. No hype, no miracle cures, just what the evidence shows, including when the honest answer is "it depends."

▸ Stay Strong: lifting, running, calisthenics and how much you really need
▸ Your Body, Rewired: creatine, protein, testosterone, diet vs exercise and more
▸ Your Mind: how your brain and everyday behavior change with age

How these videos are made: I choose every topic and check every study against the original paper. AI tools help me research, write the scripts, draw the illustrations and voice the narration. Most videos list their studies in the description.

General education, not medical advice.
