Exercise for good health

You can buy many things with money but you can't buy health, I love going to park with my son. He gets to play with his friends I get to walk with my sport shoes. I love exercise at park, sweating feel so good and I want to go everyday but I cant as weekend is family day. I hope my friend will walk with me but seems she has lot pain. She finds that the pain not going away so her decision is eat medicines. I feel going for walk no need hardworking but she finds it difficult.
