Exercise.

I don't even know. But exercise is the god-tier reigning champion of all things health. You can count on it pretty reliably to show up as a positive effect source in any health study.

"Just exercise" should be a meme at this point.

Exercise actually increases oxidative stress.

https://pmc.ncbi.nlm.nih.gov/articles/PMC7498668/

What lowers oxidative stress is nutrition, specifically selenium, vitamin C, manganese, zinc, and copper.

I knew I should be eating more soil
Breathing also increases oxidative stress but no one is going to tell you to breathe less
Selenium can elevate your PSA, so stop taking it a couple week prior to a test. It also increases fluid production from the prostate.
It's quite a lot harder than just taking a pill every day, of course.
Only because people drive everywhere. If you live in a well designed city you just walk everywhere and you don't have to do anything extra.

It's only hard because we make it hard.

I walk my kids to school every morning. And I walk to pick them up. It's a 10 minute walk to get them, so that's about 40 minutes of walking each day. I could drive and get there in 2 minutes then wait in a line. It would probably cut the time in half, but walking is better for the environment (noise, pollution, safety, wear and tear), me, and my relationship with the kids (we, y'know, talk while we walk).

There's people that live even closer that drive their kids to school. One of them lives literally 19 houses down the street from it.

I also have a rule where if I can go somewhere within 20 minutes on a bike, I'm taking my bike. Most places I go fall under this rule, and I live in what most would call a suburban hellscape.

My wife used to drive to work. Driving took longer than walking. But she still drove.

I think it's less about easy vs hard and more about the culture around driving in the US.

That's great - for me the problem is weather. Where I live it's hot, >80s Fahrenheit, >28 celsius, for 4 months a year. So unless I want to always be sweaty, I can't really walk more then 10 minutes at a time.
You sound like you live in the Midwest like I do.

I tried biking to work for a while - 13 miles. During summer/fall, it was pretty nice, I'd go early in the morning, shower at the gym, and then bike home. 2 workouts a day when the weather was fair.

The sweaty part, you'll get less sweaty as you get more in shape, both exerting less and retaining heat less efficiently due to lower BMI. But - you'll probably never not be sweaty if the distance is anything significant like, say, 13 miles.

Let's talk about colder climates. I was a consultant for a few years, and got to travel all over. I recall visiting Calgary in the winter, and some maniac dev manager biked to work every day, rain, snow or shine. 6 miles he said (helpfully translating units for me).

Carry a water bottle and take showers. Sweat is normal, if you don't like it wash it off.
Folks seem to have forgotten about sun umbrellas as well.
There needs to be a shower where you're going, and you need to budget the extra time and change of clothes.
And do the thing at dawn if you can!
In the US a large number of people have moved to suburbs in the south. On a bad year our lows are in the 90F range. Add in asphalt architecture and in the sun temps are commonly 125F+
Patient: "Doctor, it hurts when I do this." Doctor: "Then don't do that!"
Or get a dog.
It's not though.

To get a statin you have to go to the doctor, get a blood test, get a prescription for the statin, and start taking it, get blood retested, adjust dose (possibly), etc. Then you have to go to the pharmacy, pay for it and take it every single day.

To exercise you literally have to walk for 30 minutes. That's it.

Walking for 30 min isn't going to do it either.

If you have high cholesterol, you probably have to change your diet to put any real dent in it, like reduce consumption of your favorite foods.

Meanwhile a low dose statin can drop your cholesterol by 30%.

Walking for 30 minutes/day when you previously walked 0 minutes/day will have a dramatically larger mortality reduction than taking a statin.

For the record adding a statin reduced my (genetically very high) cholesterol by over 50%, and I will almost certainly take it for the rest of my life. Diet and exercise changes led me to lose over 80lbs, required 0 doctor visits, cost $0, and has completely changed my life and my likely health trajectory.

So yes take statins, but no statins aren't 'easy' unless you are very well integrated into a health care system and actively having checkups where your cholesterol levels are being checked and reviewed, which is only true of a very low % of people in the US, even those with gold plated healthcare coverage.

> Walking for 30 minutes/day when you previously walked 0 minutes/day will have a dramatically larger mortality reduction than taking a statin.

It might for all-cause mortality, but it is unlikely to reduce ASCVD mortality more than a statin, or statin + ezetimibe would. Even if your high LDL isn't genetic, once you've done the damage to your arteries, it is basically going to stay there, and treatment targets for preventing further damage at that point (or some regression, if you get really aggressive with combo therapy and get down below 50) aren't often possible with lifestyle changes alone.

Yes, if you take my statement comparing A and B for the result C, then completely change B, and also completely change C, it might no longer be true.
If someone goes from not exercising at all to walking 30 minutes a day, it will make a definite dent in blood pressure. Changing diet will add another dent. Walking for 90 minutes a day will make a bigger dent than 30. The degree of the changes reflects the degree of the results.
Homeless are walking (exercise) miles daily 365/7 yet they are unhealthy. lol
There are often other comorbidities with being homeless.
I don't know man some of those guys are absolutely shredded. Maybe they're just platonists?
Diogenesists? Diogenesers? Followers of Diogenes?
I'm low on ancient Greek knowledge, what are you getting at?
Why would they be platonists? Diogenes was the Greek philosopher who shunned material things and famously lived in a barrel. Seems like that would be the ancient Grecian philosopher that might inspire some form of voluntary homelessness.
There's a (apparently un-substantiated[0]) claim that Plato was buff; "Plato" was apparently a nickname and meant "broad" in Classical Greek, referring to his wrestlers physique.

[0] I heard this claim a long time ago, but according to Wikipedia (https://en.wikipedia.org/wiki/Plato#Life) it's apocryphal. The Talk page has a decent argument for it not being the case.

Ah fair, I meant in that they're homeless so they must live in their heads/in ideas which are more real to them (hence Plato), so they're shredded from always being active and outside.
I believe followers of Diogenes are called Cynics
Ah, yes.
