No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Hello.

Twice a day I ride bicycle for 2km along a busy city road (2x2 lanes at 50km/h).

From a health standpoint, is it recommended to wear a face mask (N95)? Does it stop exhaust fumes?

Thank you.

Great question. There's at least one study that claims they do help:

A lot of folks who operate leaf blowers and such would also benefit from wearing a respirator. I see landscapers forgetting to do this all the time. They have the eye and ear protection, but no lung protection.

leaf blowers

Seriously, those things are the worst.

I hate the two-stroke models. Electric aren't so bad.

[–] [email protected] 3 points 1 year ago (1 children)

Yeah, I was talking about the former. Electric ones are totally fine.

But the fromer ones are really super bad. They put out carbon monixide and all kind of dust and shit ... micro plastics whatever, fuck you. Point is they are so much worse than you'd think.

The exhause from those is worse than a diiesel VW with the cheating software disabled.

[–] Boozilla 2 points 1 year ago (1 children)

Agree 100%. They should be banned...some places have already banned them and it's a spreading idea.

If there is one good thing about covid, it's that I have spare mask lying aroung. I now use a mask whenever I vacuum. There is so much dust you blow in the air. I have two cats. There is cat hair everywhere, the mask can't hurt.

[–] [email protected] 1 points 1 year ago

Ugh, inhaling cat hairs :D

I got a dewalt one for pretty cheap since i already had the batteries for it, and i don't see anything wrong with it. Plenty of power and not a lot of noise.

The landscape company that maintains the condo I live in uses them exclusively to "clean" the paved common areas and every time they do, the dust blows up into the air, and then 15 minutes after they pass it resettles right back where it came from, while also leaving a fine film of dust on every flat surface in the apartment, as well as small piles of long-accumulated gunk in every corner and crevice. I can't help but think how much better and quieter this place would be if they just used brooms.

Cool, the study was done at the University of North Sumatra. I'm adding it to my archive. Thanks!!

From the Abstract/ Conclusion: "All three type of masks such as surgical mask, N95 mask, and carbon mask was effective to reduce CO levels from air pollution with the most significant was N95 and carbon mask. Fabric mask has the poorest protection from CO levels."

I'm surprised at the N95 being effective. And expect the best results would come from a fresh, well fitted, carbon filter. As for myself, I do my best to ride where the motor vehicles are not present. Our town, like many, has a decent bike/ walking trail system.

I don't know, but I guess that depends on the specific person, I biked for 10 years through the city, 7km one way, 7km back in the evening, summer, winter, never had respiratory problems, still got none about 7 years later, my problems started when I stopped. I actually gained substantially weight :) true story. Weight's gone, but what a fight it was.
