How brain cells self-destruct

I have previously written about the contribution that older workers can make in solving the talent crisis. I have also written about the reluctance of employers to hire older workers. Employers often give cognitive fitness as a primary reason for this reluctance. Psychologists know that cognitive performance can decline with age, but that some people avoid this decline by engaging in tasks that continually stretch their minds. It seems to be a matter of use it or lose it. Now comes some added weight to the use it or lose it argument from the field of neuroscience.
