Scientists love telling us what needs to be done to achieve longer, healthier lives. We know that exercise is good for heart health—ideally 45-minute sessions, three to five times per week—and some research suggests that team sports improve mental health.

As The New York Times reports, another new study is highlighting the surprising health benefits associated with certain sports in particular. Researchers say tennis is linked to a 9.7-year increase in life span, compared to 6.2 years for badminton, five years for soccer, 3.7 years for cycling, and 3.2 years for running.

These findings, published in the journal Mayo Clinic Proceedings, are based on analyses of the lifestyle choices and exercise habits of 8600 Danish people who participated in health exams and lengthy questionnaires over the course of about 25 years. Some of the participants died during that time, and researchers compared their life spans with the type of exercise they did and how often they did it. Unsurprisingly, while the study showed no causation, all sports were associated with a longer life when compared with people who led sedentary lives. The breakdown of those sports, and how good they are for your health, is where it starts to get interesting.

Even when the researchers controlled for different factors such as education, socioeconomic status, and age, tennis still came out on top as the best sport for longevity. These findings seem to support those of a 2017 study of more than 80,000 British people, which found that players of racket sports tended to liver longer than joggers.

Dr. James O’Keefe, a co-author of the new study, told the Times it’s not clear why some sports are correlated with increased longevity more than others. However, he theorized that the social aspect of certain sports plays a critical role. “We know from other research that social support provides stress mitigation,” he says. "So being with other people, playing and interacting with them, as you do when you play games that require a partner or a team, probably has unique psychological and physiological effects.”

When it comes to furnishing your kitchen with all of the appliances necessary to cook night in and night out, you’ll probably find yourself running out of counter space in a hurry. The ChopBox, which is available on Indiegogo and dubs itself “The World’s First Smart Cutting Board,” looks to fix that by cramming a bunch of kitchen necessities right into one cutting board.

In addition to giving you a knife-resistant bamboo surface to slice and dice on, the ChopBox features a built-in digital scale that weighs up to 6.6 pounds of food, a nine-hour kitchen timer, and two knife sharpeners. It also sports a groove on its surface to catch any liquid runoff that may be produced by the food and has a second pull-out cutting board that doubles as a serving tray.

There’s a 254nm UVC light featured on the board, which the company says “is guaranteed to kill 99.99% of germs and bacteria" after a minute of exposure. If you’re more of a traditionalist when it comes to cleanliness, the ChopBox is completely waterproof (but not dishwasher-safe) so you can wash and scrub to your heart’s content without worry. 

According to the company, a single one-hour charge will give you 30 days of battery life, and can be recharged through a Micro USB port.

The ChopBox reached its $10,000 crowdfunding goal just 10 minutes after launching its campaign, but you can still contribute at different tiers. Once it’s officially released, the ChopBox will retail for $200, but you can get one for $100 if you pledge now. You can purchase the ChopBox on Indiegogo here.

Mental Floss has affiliate relationships with certain retailers and may receive a small percentage of any sale. But we choose all products independently and only get commission on items you buy and don't return, so we're only happy if you're happy. Thanks for helping us pay the bills!

The Right Way to Clean Your Face Mask

In an effort to slow the transmission of coronavirus in public settings, health officials are advising that people unable to practice social distancing wear a cloth face mask. While not as effective at filtering respiratory droplets as medical-grade masks, cloth masks are still recommended as a practical preventative step.

Like all apparel, masks get dirty. They absorb sweat and germs, and they need to be cleaned. But how?

According to National Geographic, the best way to clean a cloth face mask is to take the same approach as the rest of your laundry—toss it in the washer. Laundry detergent is effective against coronavirus because the pathogen is encased in a layer of oily lipids and proteins. Detergents and hand soaps contain surfactants, which reduce the surface tension of the fatty layer. The surfactant molecule is attracted to oil and grease on one end and water on the other. The end that disrupts the oil bursts the coronavirus envelope apart. Tiny pods of surfactant called micelles trap and wash the remnants away. It’s this activity, not the water temperature, that kills the virus, though using a higher dryer temperature can destroy most microorganisms that might be lingering.

Bear in mind there’s a recommended way to take off your mask. Make sure your hands are clean, then pull it off using the straps behind your ears. This avoids contaminating the mask—and your face—with any pathogens that might be on your hands.

Medical-grade masks are trickier, as they’re intended to be used only once and can’t stand up to a wash cycle. If you have an N95 or paper mask, you can set it aside for several days, at which point the virus is likely to become inactive. But keep in mind that health officials still aren’t entirely sure how long coronavirus can persist on surfaces, and it’s possible for a mask to collect particles over time, increasing the viral load.

But what about the rest of your clothes? Experts say not to worry so much about disrobing the minute you get home. The coronavirus likes moisture and dries out quickly on fabrics. You need to be careful with the material covering your face, but the rest of your outfit can wait until your regularly scheduled laundry appointment.
