Hi, Richard,
My father's name is Richard Vargas also, and he is 90 years old. He began taking King Fu at age 65 yrs. for 20 yrs. He is a Marine and is still very strong and physically healthly. do your exercise the rest of your life and you will live a long life.
My father's handshake is very firm and he has not fat in his body, only muscles.
