Many people enjoy cycling as a hobby. Cycling is an activity that can be enjoyed by people of all ages and it is one of the most popular forms of exercise in the world.

When you are cycling, every one of your muscles (肌肉) is doing something. This hobby can make your body do all the exercise to stay fit.

Techniques

Techniques for cycling vary greatly depending on the type of cycling involved. Sprint (冲刺) cycling is a lot like sprint running and a lot of the muscles activities are involved. They give a large amount of pressure on the bicycle pedals to get them going at a fast speed.

For distance cycling, the most important is endurance (耐力) and many top class distance cyclists spend many hours doing endurance leg exercises.

Equipment

You don't need expensive equipment to get started but, there is a minimum amount needed for your health: Helmet (头盔) — Don't ever ride without one whether it is local law or not. Wearing a helmet can save your life, or at least make the difference between a bad headache and a severe head injury. Gloves — I have a pair of these, and you could consider them important. They absorb shock from the handles, but more importantly, if you crash, your hands are protected. Glasses — To some, these are a must.

Safety

Always be safe on the road. Do not be daring, do not insist on the right of way, do not break traffic, and always be as visible as possible.

A. It is a sport that uses the whole body.

B. These are a must if you ride after dark.

C. For this, one needs to have strong leg muscles.

D. It is important if you want to transport anything on your bike.

E. They block bugs and other objects from hitting you in the eyes.

F. Cycling, more than many other forms of sports, requires some necessary items.

G. If you know the most common causes of accidents, you can be always careful.

Michael Weiss has observed the mother-son bond (纽带) in killer whale groups off the Pacific coast of North America. These animals live for tens of years, yet even fully grown males "act like little kids around their mom, swimming right beside her like they're still babies".

Weiss wanted to know whether these children came at a cost — particularly, whether they hurt a mother's fertility (生育能力) . He and his team studied 40 years' worth of data on three Pacific pods (小群动物) . Sure enough, the team found a "huge effect".

In a given year, mothers of sons were less than half as likely to have another baby as were childless females or mothers of daughters. Noticeably, both a 3-year-old son and an 18-year-old son lowered their mom's chances of having more children, Weiss says.

The researchers suggest mom's favoritism toward her boys developed because of the particular social structure of these pods. When a daughter gives birth, her babies stay in the same group and therefore compete with the rest for food and attention. By contrast, a son doesn't bring more mouths into the group — he mates with females in passing pods who then go on to raise children in their own social units.

His kids are thus "someone else's problem", Weiss explains. So, it makes sense for mom to give more energy to him than to his sisters if she wants as many grandchildren as possible with the least competition. The team didn't find out exactly how sons prevented their mothers from having more babies. Weiss says he hopes to do more research in different species of whales. But now, killer whales remain an extreme example of parental care across the animal kingdom. "In other animals," he says, "at some point, you just stop depending on your mom as much."

The Lunar Codex was founded by Canadian physicist, artist, and big businessman Samuel Peralta. Growing up with a love for both writing poetry and learning about space, Peralta dreamed of sending his poems to the Moon one day. Upon discovering that some lunar landing tasks were selling spare goods space on the ships, he booked places on five tasks. While the primary goals of these tasks are to transport lunar landers for scientific experiments, private organizations have been given the opportunity to buy any spare goods space for various purposes.

The artwork included in the Lunar Codex stands for different kinds of artists and artistic forms. The collections at present have works from over 162 different countries. These include works from painters, photographers, writers, filmmakers, and more. The size of each piece of artwork will be miniaturized onto special plates that can be read with a microscope, a tool used in scientific study for making things look larger. Content such as music and movies will be saved on digital cards instead.

While the idea of humanity colonizing (殖民于) the Moon was long just thought of as science fiction, countries worldwide are now seriously considering this possibility. Samuel Peralta hopes that the Lunar Codex can be the start of art and culture and later even humanity colonization on the Moon.
