Mask-Wearing Cuts Covid by 53%

A global research study published in BMJ shows that wearing facemasks is the most effective non-pharmaceutical measure reducing COVID-19 incidence and fatalities:

“Mask-wearing is the single most effective public health measure at tackling Covid, reducing incidence by 53%, the first global study of its kind shows.

Vaccines … do not confer 100% protection, most countries have not vaccinated everyone, and it is not yet known if jabs will prevent future transmission of emerging coronavirus variants.”

“Results from more than 30 studies from around the world were analysed in detail, showing a statistically significant 53% reduction in the incidence of Covid with mask wearing and a 25% reduction with physical distancing.”

Sports Drinks

What’s big at the 2012 Olympics? Pseudoscience, bad medical research, and  hucksterism. Products like “sports drinks” Gatorade and Lucozade, sponsors of the international athletic event, claim to improve endurance and/or performance. A special feature of BMJ (the British Medical Journal) judged the claims and awarded low scores all around:

“There is a striking lack of evidence to support the vast majority of sports-related products that make claims related to enhanced performance or recovery, including drinks, supplements or footwear.”
