The bass player with the 'Love Gun' shock rock group - who formed in 1973 - thinks the band will step down from music within the next decade.
Speaking ahead of the opening of KISS' current European tour in Sweden, he told Expressen TV: ''One day it will end. And I hope on the day that we end, we end on a high note instead of going down. You don't wanna stay one day longer than when it's great; you wanna be great util the end.''
When asked how long he thinks it will be before they retire, the 63-year-old musician said: ''We probably have another five to 10 years at the most.''
The current line up of KISS sees original members Gene and Paul Stanley joined by guitarist Tommy Thayer and drummer Eric Singer, but fans who would like to see a reunion of the original line up - which included Peter Criss and Ace Frehley - will be disappointed.
Paul has said he would never share a stage with them again, adding: ''They were instrumental in what we created as a team, but they became impossible and intolerable, on more than one occasion necessitating their removal. And unfortunately when people don't really learn from their mistakes they repeat them.
''At some point you just lose tolerance. It's ultimately disrespectful to the fans to not give them what they deserve. I don't miss them.''
