IELTS Speaking topic: An age/stage you enjoyed

Describe an age/stage you enjoyed mostly in your life.
You should say:
what the age/stage was
what did you like to do back then
who you enjoyed mostly back then
and explain why you really like that age/stage.

Well, speaking of an age I enjoyed mostly in my life, I’d like to describe the year when I was about 18 years old. That was my last year of high school, before entering the university. I was the football team leader that time in my class and we played lots of football matches after class. At that time, almost all of my good friends were big football fans, so it was very easy for us to get enough guys together and then went to the playground. I really wanted to go back then because you know, after growing up, it seems to be hard to find the suitable guys and teams to play football again. Everyone seems to be busy all the time.

Although we were facing the coming examination to the universities, and everyone was so stressful, I thought it was worth spending lots of time and energy in the playground. We got a way to let off steam after endless lessons and exams; besides, after years of physical exercises, we all kept fitness and built our body shape greatly, which benefits me all the way through my life later on.
