Taking a photo every day and then sharing it online improves your happiness. That’s what scientists found after studying a group of people who joined in the photo-a-day projects.

In the projects, a group of volunteers from 20 years old to 60 were chosen by the scientists. 【小题1】 Over a two-month period, the scientists recorded the photos taken, texts added to the photos, and how the volunteers felt. After two months, the photographers also gave a phone interview.

What the scientists found was that the act of taking photos and sharing daily photos improves a person’s happiness through self-care. 【小题2】

“I have a really busy job. But I said to myself, ‘No, I will stop to relax. I’ll take a photo of the insect（昆虫）sitting on my computer or something.’ Just taking a moment is very helpful,” a volunteer told the scientists.

Besides, photo-a-day helps volunteers look back on their own life. “【小题4】 You know, the photos I’ve taken will bring back lots of good memories,” said one of the volunteers.

Therefore, the scientists find out that photo-a-day is not just a simple practice. It makes people feel happy.
