"I don’t do it all the time, [like] 12 months a year," he notes. "When you’re young, that’s what you do. [Today, I] spend three or four months on the road in a year and that seems to be quite a good balance."
The Rolling Stones are going back on the road for their rescheduled tour dates starting with two shows in Chicago, Illinois, on June 21 and 25. After 14 more stops, the tour will end in Miami, Florida, on Aug. 31.
Jagger's rep told ET in April that the singer had "successfully undergone treatment," and was "doing very well." The rep added that he was "expected to make a full recovery."
