Another lesson from your story (similar to many of my friends’) is to just have kids younger. It sounds like you started at around 35 — if people started at 30, even, fertility is higher.

We have a societal problem when the rational individual choice (to provide your children the best head start) is to wait until your fertility declines to have children.

There is also a lot of pressure on women to "have a career" which contributes to them waiting to marry and have kids. It's not really possible to optimize both being a mother and having a career, it's all tradeoffs and those who choose motherhood and a more domestic life are made to feel like they have sacrificed or lost out on something.

> 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…

Where I am from we are having centrally-heated water, so we were told that hot tap water has anti-scaling chemicals unlike cold tap water which has only excessive chlorine.

Does estrogen in food even enter the blood?

It's sold in pill form so I assume so?

Sure some gets through when ingested, however you typically have the pill dissolve under your tongue for significantly better absorption.

I did my Master Degree in Organic Chemistry where we tried to develop a male contraceptive pill. I spend a lot of time studying sperm so here is a short list of thing to avoid regarding sperm quality (not ranked): 1. Eating and drinking from plastics (This includes aluminum cans which are plastic lined) [a] 2. Heating food in ANY type of plastic [a] 3. Caffein intake [b] 4. Sugar intake [c] 5.

Ultimately, Levine and Swan say that local and global actions are needed to reduce or get rid of these chemicals in our environments. “We should find ways to prevent further decline and even reverse the trends,” Levine says. “We must avoid being complacent about it and fool ourselves that assisted reproduction is the solution.”

But assisted reproduction is extremely profitable and always has been, some powdered rhino horn to IVF; altering industries and markets is expensive and uncertain, and politicians are for sale to the highest bidder. Just 10 large donors spent $540 million on the recent US midterm elections. The fact that some prominent campaigns resulted in a loss does not mean they wasted their money, any more than a financial loss in business or gambling necessitates the end of a career.

To the extent that fiscal gain is the dominant organizing principle of human society, financial wealth is going to continue compounding one way or another to the detriment of other measures of wellbeing.

I cannot recommend highly enough having a set of glass bottles[1] at home. Fill them at the tap (or wherever), refrigerate them, take them to the gym, in the car, serve to guests. Point is to have many, keep a rotation going. Has greatly reduced reliance on plastic. 1) https://amzn.to/3H2YadV

Wouldn't metal be far preferable? Especially double-walled metal bottles that can hold liquid at a temperature.

They don't break.

I do have some glass bottles as well for occasional use by guests, but when on the go, the popular metal water bottles seem best.

There’s always a chance that there’s a dead animal in your water heater

No, my water runs through a heat exchanger

the pills are designed to be taken sublingually, not swallowed. first pass metabolism destroys most of it.
