Mika Hakkinen has ruled out following his contemporary Michael Schumacher back onto the Formula One grid.
The Finn, who like Schumacher is 41 and a former multiple world champion, retired in 2001, five seasons before his German title rival called it a day.
Asked by Gulf News' Xpress if he has considered re-joining Schumacher in F1, Hakkinen answered: "No I did not, because I knew with Formula One, you need a massive commitment from your life.
"You cannot just go there to think this is my hobby, you really have to work hard," he added.
Hakkinen said he is confident Schumacher is fully committed to his comeback.
"In my case, I looked at all those elements and I know how hard the world of Formula One is. At the moment my life is fulfilled with being ambassador for different companies like DHL, Laureus, Mercedes, AMG, the list is long," he said.
"It would first be a case of (there being) no time (to make a comeback), and it would be more to lose than gain," said Hakkinen.
