1 . The photographs that Scilla took as a 16-year-old girl on the streets of London in 1955 stayed largely in her album (相册) over the years. Scilla is now 83, and her self-developed black-and-white photos have been brought back to life after they were discovered by a teenage photographer.

Over the past year, Philip Loveday, 16, has been revisiting his grandmother’s path across the capital to carefully rephotograph the pictures. His journey through time with a camera has been especially moving, because his grandmother, Scilla, has Alzheimer’s disease (阿尔茨海默症) and has lost many of her memories.

Philip took new photos that looked like the ones Scilla took long ago, and put them in a new album. Each page of Scilla’s old album was copied and put in the new one, with Philip’s new photos on the opposite pages. Philip’s mother, Catherine Loveday, said Scilla had been happy with the new album, which had “put her back in her shoes” as a teenager.

Philip said his mother showed him the album she had found at her mother’s house. Greatly absorbed in how modern London would compare to the city photographed by his grandmother, Philip and his mother began to make trips into central London. During the trips, they had the idea of retaking the photos.

Some of the places are similar, like Big Ben. Others show how the city has modernized. Unlike Scilla’s view of St. Paul’s Cathedral from the Thames, Philip’s retake has the Millenium Bridge. When Scilla photographed the John Lewis store on Oxford Street, it was a one-storey building — now it has seven floors. Philip had to use his imagination to recreate other sights. Scilla has repeatedly returned to her new album since receiving it. Philip said: “It’s nice for her to see someone taking an interest in those photos and going back over them, and also good for her to connect her past to where we are now.”

2 . Hang your tongue out of your mouth while your eyes look upwards. Breathe loudly and use your hands to pull your head in every way. This is yoga (瑜伽) for your face.

Fumiko Takatsu, creator of the Face Yoga Method, has written six books on face yoga and has been practicing facial exercises for about 15 years. Takatsu, 50, said she came up with the idea of facial exercises after a car accident when she was 35 years old, which left her face out of its proper position. Around the same time, Takatsu said she began to notice signs of aging, but gave up using creams and beauty treatments after they became too expensive.

Koko Hayashi, 39, a face yoga instructor in Los Angeles, said she first heard of face yoga by discovering Takatsu’s work. Hayashi said she had a chin implant (下巴植入体) when she was 27 years old, but took it out because it misshaped her face. “That’s why I’m so interested in more natural beauty instead of plastic surgery (整形手术),” Hayashi said. Like others who practice facial exercises, Hayashi believes it can fix signs of aging and help reduce wrinkles (皱纹).

The question that often pops up when someone mentions face yoga is, “Does it actually work?” A study out of Northwestern University found that the exercises may help middle-aged women.

“This is a pilot study that suggests that there might be some factors of face exercise that can be helpful to at least certain patients in improving certain signs of aging,” said Dr. Murad Alam from Northwestern University.” But we need more studies to better understand exactly how much exercise is necessary to have any benefit, whether it works for men and women of different ages, and then how much exercise is needed to keep that benefit.”

Medical reporter Dr. Jennifer Ashton said that she is not sure whether face yoga works and that any benefits are most likely going to be up to the person trying it. “If you feel better after trying face yoga, it may be something you should keep doing,” she said.
