Arsenal manager Arsene Wenger is certainly not planning to retire any time soon and admits he has no idea how Sir Alex Ferguson fills his time.
The Frenchman became Arsenal boss in 1996, since when the club have won three Premier League titles, five FA Cups and have competed in every Champions League competition since the 1997/98 season.
Ferguson, meanwhile, spent 27 years at Old Trafforsd before calling it a day in June 2013 and, as it happens, the Gunners travel to Manchester United on Sunday with the hosts hoping to wrestle third spot in the Premier League table from the north London club.
But despite being at the top for almost 19 years, the 65-year-old Wenger will not be joining Ferguson in retirement just yet.
He said: "Sometimes I think, 'What is he (Sir Alex Ferguson) doing all day.' But he looks very happy in his retirement.
"He is lucky because he is interested in horses as well. When he gets up in the morning, he can go to horses, practise or training."
And Wenger, who grew up in the Alsace region of France near Strasbourg, added: "I love horses as well but I don't go to races. I like horses in general because I am a farmer.
"I rode them when I was a kid but now? No, my back could not take any riding."
