Want to learn roller skating? I have been practicing .............. for four years. Of course, people who want to learn roller skating are advised to start learning at the age of 12, otherwise they are too young. If something goes wrong, it will be a catastrophe, no matter who they are.
Remember, remember, safety comes first. Wear protective gear when practicing. Don't be afraid of jokes from outsiders. Ability trumps skill, endurance and perseverance. I believe you can succeed.
