My Favourite Subject

My favourite subject is P.E. because it helps you learn and it keeps your fitness level up. P.E. helps you learn new things like catching and hitting a ball. It also helps you if you have health issues later in life. If your wondering what P.E. means, it means Physical Education where people can jog, run or walk down their street.
