Among my favourite sports and hobbies, I like swimming the best for several reasons. Firstly, I think playing in the water could bring great joy. It also helps reduce stress and I always feel refreshed and relaxed after swimming for about half an hour. Secondly, swimming is an excellent way to keep myself fit and healthy. It helps build up my muscle strength and prevent many heart and lung diseases. Finally, besides being a great sport, swimming is also an important survival skill, because without knowing how to swim well, it could be dangerous if there is a flood, or simply if we want to play near bodies of water. Many of such accidents have occured to teenagers lately. In conclusion, swimming will always be my preferred hobby because it is not only healthy and fun but also a life-saving skill.
