What are the hobbies suitable for college students now? Besides photography and playing games, what else?

The most suitable thing is to regard sports as a hobby. There are many sports activities, which can not only exercise but also have good entertainment. College students are teenagers and full of energy, but now surfing the Internet and playing games take up a lot of their time. Due to lack of exercise, their physical fitness has generally declined. I strongly recommend that college students like playing basketball, football, badminton and other sports activities.
