Former world heavyweight champion Frank Bruno is one of the great stories of determination in boxing and professional sports history, easily.
Bruno is easily one of the most doggidly determined fighters that boxing ever saw and one of the good people from the UK over the years involved in professional sport.
He is well loved by many around the world of course.
That said, his reaction to Pacquiao fighting again at 46 soon and challenging for the world title no less is both straight to the point and also very insightful, and deep:

That will make you think, a quite brilliant analysis in some ways.
Of both what real fighters go through, in that, the fight is never fully turned off inside of them.
That’s actually who they are on the inside and who they are as people.
But at the same time, he’s on the money in terms of what exactly is important too, the unseen damage that taking too many punches and hanging around too long can do.
You’re not paid for overtime in professional boxing, get in, get out, get paid and move on from the active fighting side of it.
That’s what Lomachenko did this week in boxing no less.
Manny Pacquiao will surely look to do that after July 19th in Las Vegas if he is successful against WBC welterweight champion Mario Barrios.
Anything else like a fight with Gervonta Davis would only be an exhibition, most likely.
