I go for a decent walk most days and it doesn't require effort or get boring. It goes well with listening to headphones and relaxing the eyes on the horizon plus seeing a bit of nature and humanity in action. This does me a lot of good however the only upper body exercise I get is playing the piano! I can't see myself joining a gym or doing press-ups reliably in the long-term. I need to find a suitable hobby which ha…

VR boxing, sword fights or tennis. Synthriders is very nice

Nobody claimed we are intelligently designed.

Evolution is not perfect. We are still better at running long distances for long stretches of time than any other animal.

Ask anyone in the army how all those years of running drills have affected them as they got older. It’s not so rosy. Lots of knee problems in that group. Above average practice of running throughout life also increases likelihood of requiring pacemakers later in life.

To be fair, it was the weight not the distance that destroyed my knees and ankles. But still, I've aged a lot better than many of my friends and family who were more sedentary, so who knows.

My wife's a podiatrist. I can conjure what I've heard her tell a thousand people over the years: invest in arch supports. Shoot for the ones that run about $50 and are rigid. Don't start with the $500 custom ones, and skip the $10 soft ones you see at the pharmacy. Go to REI or a running shop or a sporting goods store and get those instead.

My knees freaking killed me when I was running. I started using the supports my wife bought for me and it instantly improved, and far beyond any placebo effect. Before: my knees ached after I ran 100% of the time. Now: they never ache anymore.

I guess there are a lot of confounding variables in there, having taken up running a few years ago my resting heart rate is very low, and I'm far more aware of it than a non-runner. I suppose folks with a family history of heart problems may take up exercise to try and get ahead of it too.

Just because our ancestors did something doesn't mean it's automatically good for your health. After all, prehistoric men weren't known for their long life expectancy.

This is a gross simplification on both accounts.

US Army veterans do have a higher rate of arthritis but their days are quite different from the "run 3-5 days a week" that most people think of when talking about recreational runners.

And the pacemaker comment stood out so I did a bit of digging and found a study [1] you might be referring to. Again, the effects were strong only in the heavy-duty-exercisers/pro/semi-pro cross-country skiier group. Additionally, this didn't offset the gains to cardiovascular or mortality risk - that group was still "healthier."

I can directly tie my mood to how much exercise I’ve had in a given week. It’s also easy, given how busy life feels, to let the proverbial frog boil in water when it comes to this. My partner often comments when I’ve been a little grumpier than usual by saying, “you should go on a bike ride.” It really works wonders on the soul (and the more physical heart and lungs) getting out for a spin in the fresh air.

Absolutely, as much as everyone says eating right, exercising and sleeping well are the answer I totally neglected myself. Boosting cardio and dropping some weight has been an absolute lifechanger

I'm not sure from where you got this because any documentary/book/article and simply real life experiences related to this subject states the opposite (take a common animal such as a dog as an example)

Earlier quoted context omitted.

Ask anyone in the army how all those years of running drills have affected them as they got older. It’s not so rosy. Lots of knee problems in that group. Above average practice of running throughout life also increases likelihood of requiring pacemakers later in life.

People in the army are also regularly carrying an extra 50 pound ruck, 25 pounds of body armor, and enough other various and sundry items to add up to about 100+ lbs of total kit. That's probably what's destroying people's knees more than the running by itself

Coupled with weeks if not more of regularly scheduled sleep deprivation so you never actually recover from any of those hard days.
