Many thanks for mentioning my website blog!Yes, tennis is a healthy sport for life, challenging both body and mind. Nice review of some of the medical and scientific studies in this area. I took up tennis in high school in the 70s. With the passing of the 80s, 90s, and 2000s decade, we are now at the start of the new decade of 2010...and it means I am starting my 5th decade of tennis...holy cow! With all the childhood and teenage obesity problems now, my hope is that more people will take up and enjoy this sport.
