A cou­ple of weeks ago, my friend and Food Net­work host, Ellie Krieger, invit­ed a few col­leagues for lunch to cel­e­brate thefitness release of her new book, The Food You Crave. We were joined by edi­tors from MORE mag­a­zine who were work­ing on a sto­ry on anti-aging. When the edi­tors asked us about our anti-aging strate­gies, with­out pause each of us talked about the impor­tance of phys­i­cal activ­i­ty. And just yes­ter­day, I read a report that men who are the most fit live the longest and that men who walk briskly for 30 min­utes a day, five days a week dra­mat­i­cal­ly cut their risk of dying. For me, phys­i­cal activ­i­ty is non-nego­tiable, like brush­ing my teeth. No mat­ter how lousy or tired I feel before going to the gym or tak­ing a walk, I feel much bet­ter after. Maybe I’ll even live longer!
