His biological clock is ticking, too
Men should be just concerned as women.
- A study from Rutgers documents age-related reproductive factors for men.
- Beyond a certain age, men risk a variety of serious hazards to their mates and offspring.
- Men planning to father children should consider banking their sperm before reaching 35.
We've often heard of a woman's "biological clock" ticking as the age window approaches during which conception, a safe delivery, and a healthy child are most likely to occur. It turns out men have a biological clock of their own. A study from Rutgers Robert Wood Johnson Medical School now identifies men's ideal reproduction window. As with women, there's reason for men to be concerned about successfully reproducing beyond a certain age, even though there's been a 10% increase over the past 40 years of infants born to men over 45, which is beyond the recommended age. Author Gloria Bachmann says, "While it is widely accepted that physiological changes that occur in women after 35 can affect conception, pregnancy and the health of the child, most men do not realize their advanced age can have a similar impact." Bachmann adds that "In addition to decreasing fertilization potential, this can also influence the pregnancy itself, as is noted by increased pregnancy risks when conception is successful." This is even the case when the woman is younger than 25.

According to the study, men 45 and older risk a range of hazards:
- The put their partners at increased risk of experiencing pregnancy complications: These include gestational diabetes, preeclampsia, and pre-term delivery.
- Infants of such fathers are more frequently born with issues: They're more apt to be premature or succumb to late stillbirth. Low birth weight, a greater prevalence of newborn seizures and birth defects are also more likely to occur. The report cites cleft palate and congenital heart disease as among these defects.
- Maturing children continue to have problems: These include a higher incidence of childhood cancer, cognitive and psychiatric disorders, and autism. "Although it is well documented that children of older fathers are more likely to be diagnosed with schizophrenia — one in 141 infants with fathers under 25 versus one in 47 with fathers over 50 — the reason is not well understood," says Bachmann. The risk of autism decreases with fathers under 25, increases at 30, stabilizes at 40, and again rises at 50.

The main issue seems to be a degradation with age of the quality of sperm. In the same way that fitness fades with age for the individual, sperm also declines. While there's not yet a consensus on the point at which "advanced paternal age" sets in, and more research is needed, the range is somewhere between 35 and 45 years of age.
Whenever it is, older men have a reduced sperm count and the quality of an offspring's inherited DNA may be sub-optimal.
Bachmann recommends that men planning to produce offspring later in life bank their sperm before hitting 35 for subsequent insemination when the time is right.
The study refers, of course, to reproduction and has nothing to say about being an older father of a partner's child with a previous mate or an adopted child.
Construction of the $500 billion dollar tech city-state of the future is moving ahead.
- The futuristic megacity Neom is being built in Saudi Arabia.
- The city will be fully automated, leading in health, education and quality of life.
- It will feature an artificial moon, cloud seeding, robotic gladiators and flying taxis.
The Red Sea area where Neom will be built:

Frequent shopping for single items adds to our carbon footprint.
- A new study shows e-commerce sites like Amazon leave larger greenhouse gas footprints than retail stores.
- Ordering online from retail stores has an even smaller footprint than going to the store yourself.
- Greening efforts by major e-commerce sites won't curb wasteful consumer habits. Consolidating online orders can make a difference.

This is especially relevant to the "last mile" GHG footprint: the distance between the distribution center and the consumer.</p><p>Interestingly, the smallest GHG footprint occurs when you order directly from a physical store—even smaller than going there yourself. Pure players, such as Amazon, are the greatest offenders. Variables like geographic location matter; the team looked at shopping in the UK, the US, China, and the Netherlands. </p><p>Sadegh Shahmohammadi, a PhD student at the Netherlands' Radboud University and corresponding author of the paper, <a href="https://www.cnn.com/2020/02/26/tech/greenhouse-gas-emissions-retail/index.html" target="_blank">says</a> the above "pattern holds true in countries where people mostly drive. It really depends on the country and consumer behavior there."</p><p>The researchers write that this year-and-a-half long study pushes back on previous research that claims online shopping to be better in terms of GHG footprints.</p><p style="margin-left: 20px;">"They have, however, compared the GHG emissions per shopping event and did not consider the link between the retail channels and the basket size, which leads to a different conclusion than that of the current study."</p><p>Online retail is where convenience trumps environment: people tend to order one item at a time when shopping on pure player sites, whereas they stock up on multiple items when visiting a store. Consumers will sometimes order a number of separate items over the course of a week rather than making one trip to purchase everything they need. </p><p>While greening efforts by online retailers are important, until a shift in consumer attitude changes, the current carbon footprint will be a hard obstacle to overcome. Amazon is trying to have it both ways—carbon-free and convenience addicted—and the math isn't adding up. If you need to order things, do it online, but try to consolidate your purchases as much as possible.</p><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank">Substack</a>.
