Exerciser is More than the Calories You Burn - Become your healthiest you Is exercise all about calories? Definitely not. There are numerous benefits from exercise with burning calories far down the list.

How many #calories did you burn?

It's a common question when it comes to #exercise but exercise does far more than burn calories. Of the many benefits of exercise, burning calories is far down this list as I discuss in this blog.

Work less, be more productive?

Study in 6 countries found 4-day work week led to:
⬆️wellbeing

⬆️job satisfaction
Likely due to better sleep, improved work ability & less fatigue. This was compared to companies that stayed with 5-day work week.

If you think electric bikes are bad, there’s a much bigger menace hitting our roads Electric bikes are a menace. They go almost as fast as a car (if the car is parking), they’re whisper...

I get annoyed by certain e-bike riders, especially those on the sidewalk, but they aren't the biggest concern on the roads to public safety.

Want to ⬆ your productivity, put your phone on silent & away.

When people put their phone on silent or in another room, attention span increased. Even the presence of the phone nearby was enough to reduce cognitive capacity & lead to 'brain drain'.

I'm disillusioned with @bsky.app. I've been using it regularly for several months and there is next to no engagement. My discover page is full of posts that have no relevance to me. And when I search for #exercise or #fitness to find my academic community most of the hits are porn.

There seems to be something unique in rowers that puts them at risk for a fib that might not be for all athletes. It might be due to the posture and the way the heart twists during the stroke.

Study didn't include a comparison to alcoholic beer, only to water.

Basically study indicates it's best to have in moderation. But going from two beers to day to two n/a beers per day is still a healthier choice.

That being said, most n/a beers have << sugar & calories than pop.

As a professor, I spend more and more time teaching my students the importance of communication (written, oral).

Because it doesn't matter how much a person knows if they haven't a clue how to communicate with other people.
