Tennis is a life time sport played all over the world. People of all age play tennis; children, teenager, parents, grandparents and great grandparents.
Tennis is one of the oldest sports. The rules of tennis did not essentially change since 1877, the year of the first Wimbledon Championship. In Europe tennis is even documented back to the 1100s.
Tennis is both, an individual sport and a team sport. You can play singles, doubles and mixed doubles. Generally, it only takes one other person to play or you work on your serve on a court or practice groundstrokes and volleys against a wall.
Tennis players come in all sizes and shapes; while many of the great tennis players are very good athletes a good tennis player not necessarily is tall and strong or muscular. Moreover, tennis is a low-impact and non-contact sport.
