In an interview published Thursday, Hemsworth told Vanity Fair that the revelation inspired him to take more time off work to be with his family.

"It really triggered something in me to want to take some time off. And since we finished the show, I've been completing the things I was already contracted to do, I'm going home and I'm going to have a good chunk of time off and just simplify. Be with the kids, be with my wife," revealed Hemsworth.

"Limitless" is a six-part National Geographic television series (available on Disney+), in which Hemsworth explores the complete potential of the human body, with episodes dedicated to the science of immortality.
