This isn't an ATCO with years of experience looking for a job. This is Joe Public starting training to be an ATCO at the age of 50. I work with lots of ATCOs 50+ who are very good controllers so I am not saying that when you hit that age then the job isn't for you.
Everyone talks about the fact that as your reactions and thought processes become slower with age then you rely on your experience more. The problem is that this fella would have no experience to fall back on.
