Im Switching from former to later and so far I find it difficult to adapt to the more circular motion even though Kempo did include some. Im Also 54 yrs on this earth and have read elsewhere on this site that to start at any age other tha 18 years old is a waste of time. I at times question, and have been sugested, that its time to go to soft styles and maybe I should . Ive had 4 years of Kempo and found that I can more than hold my own for the first 30 to 60 seconds of any encounter.Since any true fights have been found to last 14 seconds I question the validity of the age thing. Any feedback would be welcome.
