Alex Arthur believes that he can win a world title well into his 30s.
And with a string of boxers doing just that at the moment, the 32-year-old former WBO super-featherweight champion may be justified in his thinking.
He takes on Jay Morris at the Braehead Arena on Saturday night.
Ricky Burns, now the proud owner of the belt Arthur once held, tops the card against Andreas Evensen.
Yet Arthur believes that it won't be long before he returns to the top of the bill.
And he's been inspired by Juan Manuel Marquez's recent victory over Michael Katsidis at the age of 38.
That fight took place at lightweight - the division Arthur now believes he can succeed in.
"I took real satisfaction from seeing a guy like Marquez beating the much younger Katsidis," Arthur told the Scotsman.
"In world title terms, if Marquez can win a world title then so can I. That's my answer to the people who suggest I'm a 'has-been'.
"I am so desperate to win a world title - that's what will be motivating me at Braehead. I know I have to win impressively through there so that I can return to fights which will propel me up the world championship ratings.
"The old curse of making weight is history to me now and I have never been fitter or more fired up for a fight since I beat Koba Gogoladze in Cardiff three years ago. I just can't wait to get into the ring on Saturday."
