It's quite possible this video is what brought you to this channel in the first place. It was our very first foray into the world of white-boarding and remains our most popular YouTube watch.
ln 23 and 1/2 Hours, Dr. Mike tackles what seems at first like a simple question: what's the single best thing we can do for our health?
Spoiler alert: The answer is remarkably low-tech...it's physical activity!
With Liisa Sorsa's masterful doodles hand-drawings and some solid research, this video explores how regular movement can help prevent and manage a long list of health problems: from heart disease and diabetes to depression, dementia and some cancers.
This video was made back in 2012, but the core message has held up remarkably well. If anything, there is even more evidence telling us why physical activity is amazing.
What I still hope people take away from watching is that every bit of movement counts. You don't need to find one uninterrupted 30-minute block in your day, the perfect gym, or the most fashionable athletic outfit. The basic idea has stayed the same: move more, sit less, and find ways of getting physical that you actually enjoy. As Dr. Mike likes to say, the single best activity is the one you'll do.
Thanks for watching!
