Ford, 72, has five children Benjamin, Willard, Malcolm and Georgia from previous relationships and an adopted son Liam with wife Calista Flockhart.
The actor currently stars in "Paranoia" with British star Gary Oldman, comedy "Anchorman 2" and cult science fiction drama "Ender's Game" besides a small role in 'Expendables 3' where he replaced Bruce Willis.
"I think retirement's for old people. I'm still in the business, thank you. I have a young child and I want to live as long as I can to see him grow up. I have three young grandchildren, I'm enjoying my life and I want to stick around for as long as I can," Ford told the Daily Mirror.
"I'm a kinder, gentler, Harrison Ford than I was. Am I grumpy? I might be. But I think maybe sometimes it's misinterpreted. I've always been independent. So if I'm grumpy, then call me grumpy. I'm all right with that."
Ford says he has no interest in show business other than acting.
"I don't want to be in the Harrison Ford business. I don't want a real job. I never wanted a production company. From time to time I develop a movie but with partners who are willing to show up every day at the office. I take what I do seriously, but I don't take myself seriously.
