Symptoms of the virus include diarrhea and vomiting and it infects about 684 million people globally every year

Norovirus is the term for a family of about 50 strains of virus that all share one miserable endpoint: copious time in the bathroom. Every year, an estimated 684 million people globally come down with it.

Norovirus is a kind of infectious gastroenteritis, “an inflammation of the bowel and the colon that can cause diarrhea” and vomiting, explains Dr Ambreen Allana, an infectious disease physician based in Texas.

After years of worrying that running or sneezing would leave me needing fresh underwear, a quick, minimally invasive procedure changed my life

Some of my earliest memories feature my mother’s leotard-encased body bouncing to Jane Fonda with abandon. A similar carefree fluidity prevailed a decade later, as her feet struck hard-packed sand on a shorebreak jog. Twelve-year-old me panted alongside, so desperate to be made in her image that I tolerated heated cheeks and shaking quads. Their trembling barely subsided during the one stop we made, for her to wade into the waves and pee.

But it got easier to keep up after she gave birth to my youngest brother, with her squatting in the bushes every 10 minutes or so. Soon, even that wasn’t enough to staunch the flow. She gave up and switched to hiking. “I should have done more Kegels,” she quipped.

As 007 makes his gaming return, you can climb a mountain in Cairn, play a scaredy-cat in Resident Evil, and play a criminal couple in GTA VI

Live your mountaineering fantasies and brave the elements in a wonderfully illustrated climbing game. You must carefully place climber Aava’s hands and feet to make your way up a forbidding mountain, camping on ledges and bandaging her fingers as you go. Like real climbing, it is challenging and somewhat brutal.

It was the end of a fabulous decade, when spontaneous, unpredictable parties seemed not just possible but typical. A new millennium was dawning. What could possibly go wrong?

‘We wish you peace,” said Tony Blair as the clock struck 8pm. It was New Year’s Eve 1999, a Friday night, and I was on the banks of the Thames. Britain’s fresh-faced prime minister – only two years into the job – was giving a gimmick called The British Airways London Eye its first spin. The Eye was physically unremarkable and harrowingly slow, but it didn’t matter because it only had a five-year lease and definitely wouldn’t still be around a quarter of a century later, littering the skyline.

It was the end of the 90s and, as the Thatcher/Major doldrums whizzed out of view like the subplot of Sliding Doors, we maintained a Bridget Jones-like innocence and entrusted the future to guys like Blair, Peter Mandelson and Bill Clinton, who didn’t seem like (respectively) warmongers, abuse excusers or sex pests.

How do you photograph darkness? A question Sarah Lee considers with her work as the nights draw in: ‘I’ve always been drawn to photographing the darkness as the winter months draw in after the clocks go back and we head towards the solstice. I wondered why that was given that the world itself seems so dark at the moment. I realised this year that it is not the darkness I’m photographing, but, rather, the light. Always the light.’
