Grissom Gets Fat

The reason Mr. Petersen has gained weight lately is the simple fact
that he has made a serious effort to quit smoking after a health scare
about 4 years ago when he experienced a heart arrythmia or irregular
heartbeat. His doctors told him he had to quit smoking, a habit he's
had since his late teens.
 Petersen admitted to an interviewer about how hard it was to stay in
shape after quitting and has hired a personal trainer to help him lose
the weight and improve his overall health.
You should see him off-duty when he's not wearing the baggy ****rts and
chinos the wardrobe people have made Grissoms choice of clothing. Try
looking at an episode called 'Formalities' were Petersen for most of
the time wears a very well-fitted tuxedo and looks extremely sharp.
Another place to see the real Mr. Petersen, is a site with tons of
