I also wonder if obesity is also a result of this.

Re: Sperm counts worldwide are plummeting faster than we thought
#962Whenever I read about things like decreasing sperm counts or increases in cancer I always think of the same phrase, "Everything is chemicals." It just really doesn't surprise me knowing how little evaluation is done on chemicals and materials throughout the supply chain. I believe the period from 1900 to around 2100 will be looked at as this horrible era where we filled our own ecosystem with an almost unimaginable a…
Truth is, particularly the US, the only thing we really test consumer products for is lead and mercury.
That’s not true in the least at least for consumer products like cosmetics or anything ingested or rubbed on the body. Go to FDA.gov and read what it takes to get a consumer product approved.
There is a list of GRAS “generally regarded as safe”. Outside that you can’t use it.

So how do you integrate into your theory the additional fact mentioned in that article that sperm count and male health were associated? > “One can view the decline in sperm counts as a biomarker for male health in general,” says Kristensen. > In fact, a study in a 2018 issue of the journal Andrology found a higher risk of hospitalization among men who had lower sperm concentrations. Those with sperm concentrations b…
Possibly chemicals, but, alternatively, natural selection has been relaxed across the board in the modern societies since agriculture and even more after industrialization. How often do you see males literally fighting over sexual access to a female, which would select for physically healthy males? Selection pressure for intelligence may have increased, but education level is negatively correlated with reproduction,…
> natural selection has been relaxed across the board in the modern societies since agriculture and even more after industrialization
Citation very much needed.
Women nowadays accept males indiscriminately? Reproduction success is the same for everybody across the board? That's news to me and I very much doubt the veracity of such a bold claim. Natural selection is very much alive.
Re: Sperm counts worldwide are plummeting faster than we thought
#965So this trend has been going on for a while now, I looked a bit into it about 5 years ago here's what I found: - Tons of popular and legal products/chemicals are "endocrine disruptors"[1] (fancy term for mess with hormones). - The FDA/EPA doesn't deny that, they don't themselves even really require tests for long-term health effects in humans (too difficult). Instead they give animals a 1000x+ dose and look for immed…
comparing this to climate change is a false dilemma. We can and should address both, and framing it this way is unhelpful to both issues.

#966If You care, beware of the cheap stuff, cheap artificial alcoholic drinks, cheap wines - sparkling wines. We, men, will consume it happily, like drunken sailors on shore leave. They know it. Now you will say, conspiracy, but I'm talking from my experience with allergic asthma, reacting with asthma exacerbation to some products in these categories, fortunately not every.

> ever start with a hot tap for water you're gonna boil? I've been told I shouldn't do this, so I don't, but I always feel like a rube waiting for a big pot of pasta water to boil from cold when I know I could have just used my giant tank of heated water and save 10 minutes of waiting...
That's due to old-fashioned plumbing. Wayyy back in the day when water networks were fairly new they often couldn't provide the water pressure we have now, especially in hilly areas. It was fine for cold water, but not enough to pressurise a hot water tank. The solution was a header tank in the attic. This stored water from the supply and fed it down to the hot water cylinder, providing some pressure. The problem is…

Or titanium[0]. Neat fact about anodizing titanium: the colors are the result of the thickness of the resulting oxide layer and how it refracts different wavelengths of light[1].

I'd want to know that drinks aren't full of that stuff regardless of the end-user container material, before worrying about it. They're surely exposed to tons of plastics in the manufacturing process, including at times when various components are heated. Even water supplies in a house will typically have been in contact with plastics—at the treatment plant, in the house for any modern house (they're pretty much all…
> (they're pretty much all PEX now, since it's stupid-easy and fast to install, which means it's very cheap)
Also good in cold climates as they can stretch if the water expands after freezing: they'll shrink back to the original size (esp. PEX-A/Uponor) which may help reduce the chances of the house being flooded.
Once copper bursts that hole is permanent.

> With modern closed systems (from the 70s onwards really) this isn't an issue.
The water department for the City of Denver still recommends not to use hot water:
> Hot water systems like tanks and boilers contain metallic parts that corrode as time goes by, contaminating the water. Hot water also dissolves contaminants in pipes faster than cold water.

Also Vancouver (BC):
> Confused, I decided to send the question over to Metro Vancouver, which provides water to most of the 2 million residents in the Vancouver region. Bill Morrell, Metro’s media relations guy, quickly got me this answer from Bob Jones, their water quality expert. The bottom line: Use cold water for boiling.

EPA:
> 2. USE ONLY COLD WATER FOR COOKING AND DRINKING. Do not cook with, or drink water from the hot water tap. Hot water can dissolve more lead more quickly than cold water. If you need hot water, draw water from the cold tap and then heat it.
