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 . Part one concludes by introducing my suggested method for adopting this philosophy: the digital declutter. This process requires you to step away from optional online activities for thirty days. At the end of the thirty days, you will then add back a small number of carefully chosen online activities that you believe will provide massive benefits to the things you value.

6 . 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.

7 . Plastic tubes hook up to the taps and connect them to one another. The sap flows into a collection tank in the woods. From the collection tank, the Gagnes pump the sap into a ma-chine to remove a lot of the sap’s water. Then it’s moved into an evaporator in a building called “sugar house”. The Gagnes make a fire out of maple wood chips. The fire heats the sap and boils it. When it reaches 219 degrees, the syrup is ready to be made.

Syrup is poured into glass or plastic bottles. But 150 years ago, sugar makers used tin cans. These containers could prevent syrup from seeping out and allowed them to ship it far from home and helped maple become a big business.

8 . Merebeth’s pet delivery service satisfies her wanderlust. It has taken her to every state in the US except Montana, Washington and Oregon, she says proudly. If she wants to visit a new place, she will simply find a pet with transport needs there. She travels in all weathers. She has driven through 55 mph winds in Wyoming, heavy flooding and storms in Alabama and total whiteout conditions in Kansas.

9 . Katie also designed her very own “No Hungry Children” T-shirt, which is available for purchase online. A part of the proceeds from her T-shirt sales economically supports Katie’s efforts, as well as the work of Amazing Kids, a nonprofit organization that focuses on the dreams of kids like Katie.

“I think it is important to have something to strive for,” says Katie. “By planting a garden or just some seeds in a pot you can make a difference. My cabbage alone fed 275 people. If more kids did the same, we all could be helping to make a long-time dream of no hungry people possible.”

10 . However, because Leonardo was born to parents who were not married to each other, he was barred from some studies and professions. He trained as an artist after moving to Florence with his father in the 1460s. It was an exciting time to be in Florence, one of the cultural capitals of Europe. Leonardo trained with one of the city’s very successful artists, Andrea del Verrocchio. He was a painter, sculptor and gold worker. Verrocchio told his students that they needed to understand the body’s bones and muscles when drawing people.
