During holidays, you can do many things. In my opinion, swimming is better than volleyball. And, for example, volleyball is better than football or baisball. But on the other hand, it is important to spend a lot of time outdoors. Healthy is also spending time with friends because laughter is good for health. Also you can go shopping and have a lot of fun and for exaple new clothes. In the end when you have got, planty of free time, you can go to the cinema, which in my opinion is better than for example philharmonic.
