1 . Get better at judging time. Some tasks may be accurate to begin with, and some may be inflated if you are not used to using Parkinson’s Law. A timer is going to be very useful when you start doing this.

Avoid setting arbitrary deadlines and instead think about how long a task will realistically take to complete. While this might not be clear, consider past experiences as a guide.

2 . Americans spend 87% of their time indoors and an additional 6% in an enclosed vehicle. These proportions (比例) are also fairly constant across various regions of the United States and Canada. The finding that emerges is that we are basically an indoor species. In a modern society, total time outdoors is the most negligible part of the day, often so small that it barely shows up in the total.

3 . At first, she drove through Montana and then she made her first cross-country trip in 2016. After she retired in 2017, it became a full-time job all year round. Collins and her mobile bookstore have visited 30 states, stopping at festivals and events along the way. While the locations change, some things always stay the same. Collins loves meeting people and making connections. While she loves what she does, Collins doesn’t think she can keep doing it. In several years, she hopes to pass her traveling bookstore onto another bibliophile who shares the same interest and will keep it on the road.

4 . The timetable for this game-changing ability to turn white fat to brown fat is predicted to be less than five years away after human studies start. If scientists find a way to replace white fat with brown fat, it will likely mitigate risks of diseases like diabetes, heart disease, stroke, and brain disorder greatly and provide increased energy levels. That is, you become operationally younger. Bring it on!

5 . Testing nonhuman memory retention (保持) is challenging; in research studies, “it’s rare that there is a gap of several years between when an animal stores the information and when it is next required to retrieve it,” says University of Oxford zoologist Dora Biro. For a recent study in the Proceedings of the Royal Society B, Biro and her colleagues compared domestic homing pigeons’ paths three or four years after the birds established routes back to their loft from a farm 8.6 kilometers away. The study built on data from a 2016 experiment in which pigeons learned routes in different social contexts during several flights — on their own or with peers that did or did not know the way.
