He's 38 now, turns 40 in 2018.
Do you think he will still be fighting in 2019 at the age of 40?
If he keeps fighting guys like Vargas and Horn, I see no reason why he wouldn't be.
Pac will be getting beat up by prospects when he's 45 if it can make Arum 10 cents...
He should fight twice this year as long and the second is Crawford and retire, win or lose...

Manny Pacquiao will continue to fight for as long as someone somewhere is willing to pay to see him fight; as the man himself has said, he needs to keep fighting to support his family.
Whether Bob Arum can manufacture a run that long for Pacquiao (to get to that point, you're basically looking at 5 fights) is another story.
The US audience is already done with Pacquiao; Macau may have somewhat continued interest, and Australia/Phillipines are there for at least one novelty fight. Does Arum have five fights to work with without getting Pacquiao washed by Crawford? not too sure.
