For the last year and a half, we’ve heard that six feet between you and the next closest person is a safe distance. But a new study is calling that into question. The study in the journal Sustainable Cities and Society looks at the impact of building ventilation on the effectiveness of social distancing… and finds that when people are unmasked indoors, six feet may not be enough to prevent transmission of airborne aerosols. The worst ventilation configuration for Covid is the kind found in most homes… with ducts at the floor pushing air toward elevated exhaust vents.
Eating green vegetables and fiber can cut your risk of colon cancer in half… but now scientists are honing in on which vegetables are best. And it turns out that spinach is near the top of the list. A study in the journal Gut Microbes finds that spinach can even help prevent colon cancer in people who’ve inherited bad genes that normally cause hundreds of tumors in the colon.
And finally…where you live may protect you from dementia. Three new studies in the Journal of Aging and Health and Wellbeing, Space and Society show that people living in neighborhoods offering socialization and physical activity are about three years younger in terms of brain health. Add in intellectually stimulating places like museums, colleges and libraries… and it makes residents about five years younger.
