There are geezers (and you know who you are) who never quite mellow. They cannot shake their natural competitiveness. A lot of these very active seniors will be at the 2011 Senior Games being held March 26-April 3 at Stanford and other sites around the Bay. Open to anyone over 50, there are 14 competitive events including swimming, track and field, golf and race walking. Come watch and be inspired. Admission is free. Check for postponements as the recent rains have wrecked havoc with field conditions.
