Is it too late at our ages to take up a new sport? Not if it’s pickleball, a fast growing (but not killingly strenuous) recreation with wooden panels and plastic balls, that combines ping pong, badminton and tennis. Named after the originators’ dog Pickles, there are now millions of adherents and courts around the Bay Area including the newest ones at Cedar and Rose in Berkeley. Get moving and take your choice of singles or doubles games there. No fees whatsoever and free lessons on Saturdays.
