I know by experience being all the day in front of the computer can be an attractive option for people who do informatics, stream videogames, write content, etc.
But you should employ at least 1 hours or 2 to make some physical exercise to have a better life quality.
Here is somethings you could do:
- Join a real sport. Basketball, martial arts, voley. Any thing that can help you to achieve a more active style of life, you do not need to become a professional, only do it for fun and health.
- Take a walk. Walking can be a relaxing activity and can help you getting new ideas while keeping you active, avoid using the smartphone while doing so and enjoy the real world to achieve the best results.
- Take your bike. Bike nowadays is a good transport media, but you can use it simply for fun without being in a hurry.
- Do runnig with your friends. It may help you to retake real life relationships while improving your physical and mental health.
There are many more options, but this can give you a brief idea of what can you do to have a more active life.
