Pregnancy is a life experience I’d rather avoid. That doesn’t mean I’m selfish

By
I recently conducted a very scientific study in the pub with some straight male friends. “Have you ever wanted to experience pregnancy?” I asked. The answer was an emphatic “absolutely not”. In the interests of methodological rigorousness, I rephrased my question. “Do you ever feel sad you aren’t able to experience what it’s like to grow a human inside you?” Again, 100% of respondents answered with some variation of, “Hell, no.”

My investigations were prompted by a scientific study published in the journal Human Reproduction. The official title of the study is Parity Associated With Telomere Length Among US Reproductive-Age Women, but a more accurate title would be Yet More Evidence That Pregnancy Is Torture. Not only does pregnancy mess with your hormones, it appears to mess up your DNA; giving birth may add the equivalent of 11 years to a woman’s biological age.

This doesn’t necessarily mean having kids will send you to an early grave, just that giving birth seems to cause your cells to age. The research looked at blood samples from almost 2,000 US women aged from 20-44 and found that those who had given birth had telomeres that were 4.2% shorter than those who hadn’t. Telomeres are like protective caps that cover the ends of our chromosomes; over time they get worn down, and shorter telomeres have been linked to certain physical signs of ageing such as grey hair, along with age-associated health problems, including heart failure.

FIA’s Jean Todt defends Halo F1 system from ‘childish’ Toto Wolff criticism

By
The president of the FIA, Jean Todt, has issued a robust defence of his organisation’s decision to impose the Halo cockpit protection system on Formula One this season. Todt dismissed criticism from the Mercedes executive director, Toto Wolff, as “childish” and stressed that the FIA would not shy away from making difficult decisions in the interests of safety. The Halo device will make its race debut at the opening round in Melbourne but has attracted criticism on aesthetic grounds and because it is in contradiction of the spirit of an open-cockpit series. Mercedes confidence is an ominous sign after Barcelona F1 testing | Giles Richards Read more Wolff has said he would remove it with a chainsaw if given the opportunity but Todt rejected his stance. “I will not react to whatever has been said.
