"I'm 31 now and I don't think that bands should keep going past 33," Coldplay frontman -- and former SPIN cover boy -- Chris Martin told U.K. newspaper The Daily Express [via NME.com], fueling speculation that the band's days are literally numbered. "We're trying to pack in as much as possible," he added. "Up until the end of next year, we'll just go for it in every sense."

Martin's assertion is apparently based on some Seinfeldian desire to go out "with a blast" while the band is still on top, but we think he might also be worried about the publicity shots. "We've still got most of our hair," he added as further justification. "We can still fit into our musical trousers and we've got to make the most of that."

Or… maybe Martin learned a thing or two about retirement while kickin' it with Jay-Z, perhaps?
