All I can go on is my personal experience which was putting older workers into jobs that have inherently high rates of context switching didn’t do well, while younger workers doing the same job thrived. I agree with you that there maybe other confounding variables and that there are certainly older workers that are able to thrive in such jobs, just my experience makes me wary. I am also wary of putting younger workers into positions where sustained focus is required. Ultimately neither old nor young workers are bad, they just have different strengths and weaknesses and you need to match the best person to the job.
