Roy Hodgson is taking inspiration from UK broadcasting veteran David Attenborough as he prepares to set a record as the oldest manager in a Premier League match.
The former England boss admits it will be special to move beyond Robson's tally but insists age is not necessarily any measure of ability.
He pointed to the continued success of Attenborough, the noted naturalist and documentary host, who will turn 93 in May.
"It's an achievement I can be happy about - if you call getting old and still being in a job an achievement," Hodgson said.
"I still enjoy this work, I'm always looking forward to the next game. It's nice to still be in a job like this at the age I've reached. I think age is definitely a number. There are people who are older than me who show no signs [of retiring].
"I don't know how old Sir David Attenborough is but most of us think he's very, very good. He was good then and still good now. If I were being honest, at the time Sir Bobby set that record and he was doing well, I probably wouldn't have thought I'd ever get close to the milestone."
But despite Palace climbing to 13th in the Premier League, a place behind Leicester, Hodgson remains focused on the battle against relegation rather than his record.
"I've never given it much thought. I've been obliged to recently," he said. "My views regarding age haven't really changed. You're as old as you feel. It's a milestone, a historical mark I guess I can be very pleased about. Otherwise I don't pay any great attention to it.
"Achievements are often more interesting to you when you look back on them. When you're in the middle of an important job, fighting for Premier League points, there isn't much time to reflect on the journey you've been on.
"Luckily my age doesn't ever come into my thoughts. I made a conscious decision to stop at 60. I made a decision to stop at 50. It doesn't matter what it says on my birth certificate.
"You've got to like it, to enjoy the work. You've got to maintain a certain amount of youthfulness in your demeanour, look after yourself and be very lucky to be given jobs where you can hopefully make an impact."
