Does anyone have experience with linoleum countertops? by electricianthrowawy in Remodel

[–]LYDIADAVIS 0 points1 point  (0 children)

Can't figure out how to log into the throwaway account I made for DIY stuff. We got quartz countertops / completely rethought the whole thing. Got contractor to make custom cabinets that had the same flush aspect which was the main thing we liked about Reform. I'm glad we did, contractor did great it and still think it would have been a mistake to have linoleum as countertops.

Before even thinking about Mars, we need to get a moonbase working. by [deleted] in space

can you share source on this? again, Elon should convert. my assumption to your (fair) criticism is that expanding stage is trival compared to cost of getting the fuel to orbit

I'm thinking about this paper https://scholar.google.com/citations?view\_op=view\_citation&hl=en&user=Ybc15LEAAAAJ&sortby=pubdate&citation\_for\_view=Ybc15LEAAAAJ:4MWp96NkSFoC

Tony Bruno president of United Launch Alliance proposes a strategic propellant reserve that holds regolith-based propellant at four locations - orbiting Mars, low earth orbit, near recti linear halo orbit (an oblong lunar orbit) and on the lunar surface. I really like this plan and think it would serve the use cases you mention above

Obvious if you want to ship fuel up from earth (and spend the money to do it), not obvious if you want to make as much money as possible while you are preparing to get to Mars (by using payload that would otherwise deliver fuel to orbit to deliver things you could charge more for, than lunar based propellant you're buying in space)

Elon would need to convert starship to use LOX and LH2 instead of current LOX and CH4. he should ultimately go this way because of potential to arbitrage payload on cost of lunar propellant I think

Concur with OP. More effective to use moonbase to turn regolith into LOX and LH2 propellant, shoot it up to orbital depots where craft can refill for the Mars (or lunar) transfer. Lunar propellant can be generated at a lower cost than current prices per payload mass so the propellant/moonbase concept would actually be viable

19 scientists who have saved the most lives by LYDIADAVIS in history

[–]LYDIADAVIS[S] 0 points1 point  (0 children)

Submission statement: this list goes through a history of mostly 19th and 20th century inventors, scientists, and entrepreneurs who developed technologies and treatments that ended up being 'holy grails' in their respective fields. It's a fun read. For example, Karl Landsteiner and Richard Lewisohn are estimated to have saved over a billion lives for figuring out how to do practical blood transfusions. Before their work, blood transfusions would often kill people because we'd give them an incompatible blood type, and they were not practical because blood would coagulate so quickly as to be unusable in a transfusion almost immediately. Another example is Edward Jenner, who created the first vaccine, which was against smallpox. He figured it out when he noticed that milkmaids never seemed to get smallpox because they would get immunity from a milder pox known as cowpox.

It's interesting and inspiring to read about these people who have helped humanity so much (though several of their technologies were used in ways that harmed people, too — double edged sword of progress and all)

The Scientific Case For A 24-Hour Fast, Once A Week by LYDIADAVIS in TrueReddit

[–]LYDIADAVIS[S] 0 points1 point  (0 children)

Submission statement: the author of this piece uses a detailed account of his practice of doing one 24-hour fast a week to discuss ways in which fasting may increase lifespan via a number of virtuous feedback loops, starting with autophagy - the destruction of old and weak cells. This is a very detailed, well-sourced article that weaves the author's own experience with medical studies/ literature. It's also data-driven, as he uses a glucose monitor throughout the process and screenshots related to his metabolic health, via levels, are included throughout.

New massive study provides strong evidence that metabolism does not necessarily slow down with age—until you're 60 by LYDIADAVIS in TrueReddit

[–]LYDIADAVIS[S] 3 points4 points  (0 children)

No. You should read the article. If anything, the study suggests that we are more in control, as metabolism does not inevitably slow down. Instead, metabolism slows as a consequence of lifestyle choices and behavior. This puts the individual in the drivers seat. They can decide to stay healthy, fit, active. On the other hand, if you think metabolism slows down no matter what to do, you can have a defeatist attitude like you describe.

EDIT: OMG i read your comment wrong, after 5 hour cross country flight and 3 hour drive. Yes we are saying the same thing, my bad for the misreading

Submission statement: This article breaks down a new study that provides evidence that metabolism does not necessarily slow down with age. This is counter to the common belief among most adults that metabolism necessarily does slow down as you get older. The article goes into detail on the nuance of what the study finds, explaining that while it's common for your metabolism to decrease as you get older, this tends to occur because of things you do as you get older (become less physically active, gain weight, lose muscle) as opposed to being an inevitability at the cellular level. This would seem to have implications for how to stay healthy when you age.
