So I just picked up the racket sport of Tennis. I play individually but it can also be played between two teams of two.
That sounds great, ive always wanted to get into tennis sports but dont really know much about it, is it difficult? 
It can be but practice and you will become better. The tennis ball is rubber but hollow. Its also covered in felt.
Yeah practice is always something that can really make you better at it. Dont they have tennis at the Olympics? 
They do have tennis in the Olympics. The sport can be played a all levels which is great for all ages and levels of society.
thats great, Id always wanted to play but I think im too skinny and not fit enough, I bet it takes a lot of upper body strength. 
Tennis is great for getting in shape. It was once called lawn tennis when it was invented in England in the late 19th century.
