It is likely that most people have the shared feeling: how come Christmas appears to come around quicker and quicker each year? Questionnaires by psychologists have shown almost everyone feels time is passing faster now compared to when they were half or a quarter as old. Most strikingly, lots of experiments have shown that, when older people are asked to guess how long the time is, or to "reproduce" the length of periods of time, they guess a shorter amount than younger people.

In 1877, Paul Janet suggested the proportional theory, where a child of 10 feels a year as 1/10 of his whole life while a man of 50 as 1/50, so the subjective sense of the 50-year-old man is that these are insignificant periods of time.

There are also biological theories. The speeding up of time is linked to how our metabolism(新陈代谢) gradually slows down as we grow older. Children's hearts beat faster than adults'. They breathe more quickly. With their blood flowing more quickly, their body clocks "cover" more time within the space of 24 hours than ours do as adults. On the other hand, older people are like clocks that run slower than normal, so that they lag behind, and cover less than 24 hours.

In the 1930s, the psychologist Hudson Hoagland found body temperature causes different perceptions of time. Once, when he looked after his ill wife, he noticed she complained he'd been away for a long time even if only away for a few moments. Therefore, Hoagland tested her perception of time at different temperatures, finding the higher her temperature, the more time seemed to slow down for her, and that raising a person's body temperature can slow down his sense of time passing by up to 20%.

Time doesn't necessarily have to speed up as we get older though. It depends on how we live our lives, and how we relate to our experiences.

Jeremiad Oleita thinks she may have a partial solution for two of our country's persistent problems: garbage and poverty. It's called the Chip Bag Project. The 26-year-old student and environmentalist from Detroit is asking a favor of local snack lovers: Rather than throw your empty chip bags into the rubbish, donate them so she can turn them into sleeping bags for the homeless.

Chip eaters drop off their empty bags at two locations in Detroit: a print shop and a clothing store, where Oleita and her volunteer helpers collect them. After they clean the chip bags in soapy hot water, they slice them open, ay them flat, and iron them together. They use liners from old coats to line the insides.

It takes about four hours to sew a sleeping bag，and each takes around 150 to 300 chip bags, depending on whether they're single—serve or family size. The result is a sleeping bag that is "waterproof, lightweight, and easy to carry around, " Oleita told the Detroit News.

Since its start in 2020, the Chip Bag Project has collected more than 800, 000 chip bags and, as of last December, created 110 sleeping bags.

Sure, it would be simpler to raise money to buy new sleeping bags. But that's only half the goal for Oleita—whose family moved to the United States from Nigeria a decade ago with the hope of attaining a better life—and her fellow volunteers. "We are dedicated to making an impact not only socially, but environmentally, " she says.

As Oleita said, "There's the symbolism of using bags that would otherwise land in the rubbish and using them to help the homeless. It's a powerful reminder that environmental injustice and poverty often go hand in hand. "

While travel is restricted during this time, here are some amazing places around the world to daydream about and look forward to visiting one day in the future.

Lord Howe Island, Australia

The island in the Tasman Sea lies between Australia and New Zealand and is just 10km long. Despite its complete isolation, the island is populated, by around 380 people and the number of tourists is limited to under 400. The island is known for its geology, birds, plants and marine life, while cycling is the main mode of transport on the island, thanks to its virtually untouched forest and the fact that many of its plants and animals are found nowhere else in the world.

Thor's Well, Oregon

Also called "the drainpipe of the Pacific" or even sometimes, "the gate to hell", the hole appears to swallow the Pacific Ocean. Geyser-like ocean sprays erupt in winter time, thanks to ocean pressure and the gusting wind. It looks more dangerous than it is though; it is in reality just around 20 feet deep. The natural bowl is spectacular to watch, particularly during low tide when the sea rises towards the surface before draining back down into the depths of the rocky hole again.

Keahiakawelo (Garden of the Gods), Hawaii

Hawaiians call Keahiakawelo "wahi pana", which means celebrated, noted or legendary places which have cultural significance. As legend goes, the priest of neighboring Molokai island, a man named Lanikaula, was angry at the people of Lanai, so he lit a fire wishing ill will to the island's people.

Balamku (Cave of the Jaguar God), Yucatán Peninsula, Mexico

The cave was rediscovered accidentally in 2018 by archaeologists who were searching for a sacred well. The seven-chambered cave was initially discovered in 1966 but was sealed up and forgotten about. Caves were considered openings to the underworld, and this one is no different. The name means jaguar god, which they believed had the ability to enter and leave the underworld at will. The cave is so unexplored that archaeologists are still mapping it out.
