• Very low cardiovascular fitness is associated with a roughly 400% higher risk of death than high fitness levels, dwarfing the mortality risk linked to smoking.
• Current US and UK physical activity guidelines are built around minimum thresholds, not optimal health outcomes, and a Cambridge researcher argues they need a full overhaul.
• Protein recommendations in the UK haven't been updated since 1991 and were never designed to help people thrive, only to prevent deficiency.
• Higher protein intake is linked to better muscle mass, healthier aging, improved fat loss, and potentially better pregnancy outcomes, but current guidelines fall well short of what the science supports.

The new law that passed last month makes it illegal to buy, rent, or fly a drone without prior approval from the authorities. Users must also complete an online training session and pass a test on drone regulations.

Under the new rules, drone users are also not allowed to repair or replace their drones in Beijing. Not only that, but a drone in a repair shop must be picked up in-person, rather than sent back by delivery.

The BBC reports that drones must now be registered before being brought into and out of the Chinese capital.

“I have to apply for permission for each flight, which is very inconvenient,” drone enthusiast Steven Wang tells CNN . “And starting this year, the wait time is getting longer, and the reasons for rejection are becoming more vague.”

Despite China being the birthplace of the consumer drone industry, it is increasingly difficult for hobbyists to fly there. Beijing authorities say that the rules are made to “strengthen the management of unmanned aerial vehicles” and “safeguard the security of the capital.”
