I exercise my brain - does that count? I even get off the sofa occasionally, like to get water and Food! I’m very anti exercise! My great aunt lived to 106 ate lik a horse, weighed 96# soaking wet, saw 3 centuries, turned her food white with salt, was a little deaf because she worked at the bummer plant (Lockeed) as a Rosie Riveter during WWII, was a true old maid and God fearing Christian! Plus she never exercised! She was quiet and nobody could pull anything anything on her. You would have liked her. I think it has more to do with genetics!
