This will sound unbelievable to most people. (Not to me!)
A Danish study followed 30,000 people of all ages for 15 years.
Those who cycled to work were 40% less likely to die (of all causes)
over the study period.

In his new book, @peterwalker99 shows how even modest amounts of exercise, built into the daily routine, are a "Miracle Pill."
But car-centered, convenience-oriented cities make this very difficult.
We've engineered exercise out of our environment. https://www.treehugger.com/in-praise-of-stairs-5101268

Astonishing stats from his book: avg. Canadian adult walks only 4,800 steps a day. (Avg. car-free Amish averages 18,500, without thinking of it as "exercise.")

Average American is so inactive that, if current trends continue, by 2030 s/he will expend only 15% more total bodily energy in a week than somebody who spends entire 7 days in bed.

Amazingly, if you build just a small amount of exercise into your day, the long-term effect will be as dramatic as the most potent medical treatments we have.
Walking or cycling with your kids to school, instead of driving.
Taking the stairs, instead of the elevator...

You only need 20 minutes or so a day. A couple of generations ago, people managed that effortlessly.
Now the environment we've built for ourselves makes even this minimum difficult to attain.

"Convenience" is killing us.
