SPORTS. Could anyone correct this text?

In my opinion, sport is very important for health. From my point of view, sport not only keeps you healthy physically, but also helps you to be psychologically well. In fact, physical education should be a compulsory subject throughout adolescence and all youth.

I like to practice sports several times a week. I play paddle?, I go mountain biking and I occasionally go skiing. However, my favorite sport is football, but I don't play, because when I was younger I was injured my tibia during a football game and I decided not to play anymore. However, I like to watch football games on TV.

The second sport that I love is skiing, but I only go skiing once a year, because it is a very expensive sport. When I go skiing I have to rent skis, boots and sticks, and I have to buy the pass that allows me to slide down the slopes. All this costs more than a hundred euros.

Third is the paddle?. It is a sport that I like and that is quite cheaper than skiing. For ten or twelve euros you can rent the court. However, the downside of it is that four players are needed, so sometimes it's hard to find people who can play the same day, at the same time.

Finally, mountain biking allows me to leave whenever I want. Although it is best accompanied with another person, is not strictly necessary. So, when I’ve had a stressful day at work, I take my mountain bike and ride along the roads to see beautiful landscapes and relax.
