A recent study by a South African academic, Professor Nonhlanhla P. Khumalo, Head of Dermatology at the University of Cape Town, says people are badly exposed to blood-borne viral infections during haircuts at public barbershops. Its findings apply to any similar environments in Africa, including Zimbabwe and elsewhere. The November 2025 study, published in the South African Medical Journal, investigated the risk of transmission blood-borne infections and viruses such as HIV, Hepatitis B (HBV), and Hepatitis C (HCV) through haircuts and their association with conditions like Folliculitis Keloidalis Nuchae (FKN). Its core objective was mainly to determine if the popular "chiskop" - clean-shave haircut as it is widely called in township lingo in South Africa and the condition Folliculitis Keloidalis Nuchae (FKN) (keloid-like scars on the back of the head) - increase the risk of acquiring blood-borne diseases. The findings are damning. Men who regularly experience visible bleeding during haircuts are significantly more likely to be HIV-positive (OR = 2.51). In a cohort of over 1 100 men, the overall seroprevalence was 17.2% for HIV, 6.9% for HBV, and 0.4% for HCV. While FKN itself was not directly associated with a higher prevalence of these viruses, bleeding caused by the haircutting process is a confirmed risk factor. One clipper from each barber was collected immediately after it had been used for a clean shave haircut. Each clipper was rinsed with phosphate buffered saline and submerged in viral medium. Polymerase chain reaction testing was then used to identify a blood specific RNA marker, haemoglobin beta, as well as hepatitis B virus and HIV. Chiskop or clean shave haircut was found to be the most popular yet risky hairstyle, accounting for 78% of clients. Of the clippers collected, 42% tested positive for haemoglobin beta, confirming the presence of blood. None however tested positive for HIV, while four clippers, representing 8%, were positive for hepatitis B virus. Two clippers were positive on qualitative hepatitis B PCR testing. Genetic analysis showed one sample clustering with genotype A sequences from South Africa, India, Brazil and Martinique, while another clustered with South African genotype D sequences identical to a subtype D sequence previously identified in Gauteng province. While HIV was not detected on the clippers in that specific sample, 8% of the clippers tested positive for Hepatitis B (HBV). The DNA copies found were sufficient to pose a legitimate transmission risk. “This study confirms that there is significant contamination of barber hair clippers with blood and blood-borne viruses,” the study says. “Hepatitis B was detected with enough DNA copies to pose a risk of transmitting infection. Although HIV was not detected in this small study, the risk of transmission should be quantified.” Khumalo has a long history of research on haircut-associated virus risks, with the following studies associated with her works: "Blood and virus detection on barber clippers": Published in the South African Medical Journal in March 2018. "Invisible Bleeding from Clean-Shave Haircuts": Published in the journal Dermatology in October 2013. "Folliculitis keloidalis nuchae, bleeding from haircuts, and potential HIV transmission": Published in AIDS Care in May 2008. One of her critical contributions is the identification of "invisible bleeding". Using sensitive RNA markers (hemoglobin beta and albumin), Khumalo's team proved that blood is often present on the scalp after a clean-shave haircut even when there are no visible injuries or cuts. This suggests standard barbering practices can facilitate blood-to-tool-to-blood contact without the barber or client being aware of an injury. In her recommendations, Khumalo called for more public awareness of viral infection risks, barber training, and stricter adherence to clipper sterilisation protocols in salons to prevent the spread of HBV and HIV.

What struck me about this video of “fake virginity blood” being sold in Northern Nigeria is not the product itself, but the moral education that makes such a product necessary. Deception does not appear out of nowhere. It is learned. And as bell hooks reminds us, patriarchy is one of the most effective schools of deception we have. When a society places impossible and one-sided moral demands on women, while demanding almost nothing from men, it does not produce virtue. It produces performance. Virginity here is not really about sex. It is about proof. About a woman’s body being turned into evidence. The hymen becomes a certificate of value. Blood becomes currency. Honour becomes something that must be staged convincingly enough to satisfy male judgment. Growing up in Northern Nigeria, many of us heard the stories in whispers. Rumours about the lengths people went to preserve the myth of virginity. Women avoiding vaginal penetration entirely. Anal sex used as a workaround, so that on the wedding night the illusion could be completed. Blood shown. Husband reassured. Honour “intact.” Everyone colluding in a lie that everyone knows is a lie. This is not moral decay. It is moral absolutism doing what it always does. It teaches people how to deceive in order to survive. bell hooks writes that patriarchy teaches men and women to lie in different ways. Men learn to lie about vulnerability. They are trained to suppress fear, tenderness, emotional need, because honesty would cost them power or status. Women, on the other hand, learn to lie to stay safe. They learn that telling the truth about their bodies, desires, or histories can bring punishment, abandonment, or violence. So women learn concealment. Performance. Strategic silence. Seen this way, fake virginity blood is not shocking. It is logical. It is a market solution to a moral contradiction. If a woman’s worth is reduced to an anatomical fiction, she will find a way to manufacture that fiction. And we must ask the obvious question: where is the demand for virginity from men? Where is the obsession with their bodies as proof of moral worth? Where are the rituals, the products, the inspections? Men are assumed whole by default. Women must prove themselves worthy. The tragedy is not that women deceive. The tragedy is that honesty is made dangerous for them. A society that truly cared about morality would start with symmetry. It would care less about blood on bedsheets and more about kindness, responsibility, and mutual respect. Until then, deception will continue to flourish. Not because women are immoral, but because patriarchy demands purity while rewarding power. And whenever purity is demanded without justice, lies will follow.

Every man lives two lives. The second begins when he realises that he can max out hypertrophy in 15 second sets. Four or five reps build muscle. The last four or five, where the bar slows on its own whether you like it or not. That is where the high-threshold motor units finally get called up. Where the cross-bridges are attached in maximum number at once. Where the fibre takes the tension it has been waiting all set for. Mechanical tension is the only language the muscle reads. It does not have a second one. Everything either side of that is filler, and somebody is paid to sell you filler. Tempo is filler. You are 30 to 50 per cent stronger lowering a weight than lifting it, so no descent on earth is slow enough to threaten you. Drag it out and all you have done is put a lighter weight on the half that counted. The pump is filler. Lactate infused straight into the blood grows nothing. Blood flow restricted on a resting muscle grows nothing. Swelling is a feeling and it gets no vote. The mind-muscle connection is filler. You cannot instruct a muscle in which fibres to use. You tell it to contract. The load decides the rest. So: a weight where the fourth rep slows by itself. Drive it. Stop one short. Rack it. Fifteen seconds. That set has already delivered everything your three sets of twelve spent forty minutes promising. Nobody has ever built a business on fifteen seconds of hard work, so they built one on everything you could bolt onto it.

Some kind organisations are posting messages urging people to leave out water for our precious wildlife in this hot dry weather, which is brilliant, thank you. But this rumour doing the rounds that hedgehog mums abandon their nursing babies is utter nonsense. Hedgehog mums are the most patient, loving parents you can imagine. They are tightly bonded and would NEVER willingly abandon their babies. But they die. They die because lactation places a massive continuous drain on a mother's water reserves. If she is deprived of water, her body is forced to pull from its own tissues and blood supply to maintain milk production, resulting in rapid blood volume depletion and thickening of the blood. Producing milk requires a massive amount of calories and water. If resources are scarce, the mother's body goes into a negative energy balance, which drastically accelerates the depletion of her internal reserves. But they stay with their babies, protecting them, loving them, literally giving them their last drop of life. The starving dehydrated babies eventually stagger out of the maternity nest, instinctively seeking sustenance. By the time they are found by humans they are so near death and their dehydration so extreme that only subcutaneous fluids from an experienced rescue can save them. All this heartbreak and tragedy can be avoided, and rescues freed from bed-blocking babies, if only everyone simply puts out a dish of water. Right now. And tonight. Front and back. Under cover in the shade, if possible. A turn of the tap can save so many lives.❤️
