The Blondie singer, who turns 66 in July, revealed that she still wants to achieve things with her life, and has no plans to retire.
"I don't know if there's anything that I'm really scared of now, other than mortality," Harry admitted to Attitude, when asked about her greatest fear. "I feel that I've achieved a lot but I don't want to stop."
"I want to keep doing things," she continued. "I don't want to retire."
Harry also said that although she will have to stop performing one day, she doesn't ever intend to stop working entirely.
"I know that I can't front a pop or rock band forever, but I would certainly like to keep writing or start a clothing business," Harry explained.
When asked whether she believes in the existence of an afterlife, the popstar also revealed that she doesn't think that anything happens when we die.
"How does that make me feel about this life?" she added. "Make this as good as possible."
Blondie will release their ninth studio album Panic of Girls on June 1.
