привет всем помогите пожалуйста с англ.яз номер 5

Sport plays a big role  in the lives of many people. 
I don't like sport because I am fond of science. 
People say that sport can help you to keep feet. 
However I know many cases when people were injured doing sports. 
Besides our life is so busy, so it is difficult to find extra time for sport. 
I do my morning exercises and I think it's enough for me.
