The debate concerning the outdoor and indoor activities can result in numerous roads. I think that it is necessary to take in consideration the both axes before exposing my opinion.

The outdoor activities are good for the health and very varied. It is easily possible to practise a sports and funny activity such as the soccer, the basketball, the volleyball, and many others.
But the outdoor activities are not limited to physical activities, a simple stroll in a park with friends and an afternoon shopping are very nive.

The indoor activities are totally different given that the space is reduced, but they are also pleasant. After a long day, it is pleasant to arise with our family to watch television, to make a party game, to cook, to dance, and especially to sleep.

Personally, I like sport, see my friends, go shopping and the fresh air. I appreciate a lot travel and discover new landscapes and new persons. But in winter, when the weather is very cold, I prefer stay warm at my home and read a book or listen music.
In conclusion, my opinion is mitigated but my preference turns unmistakably to the outdoor activities.
