Bias is bad for the well-being of older people. Here's how the fitness industry can take on ageism.
At what age does a person become old? Is it 50 or 65 or 75? I've known healthy 75-year-olds who could outrun, outswim and outlift me, and I've known diseased 60-year-;olds who'd be short of breath walking to the mailbox.
