Over the past year, Chris Hemsworth have been exploring the science of living longer, doing everything he can to hold back time. But whatever he does, sooner or later, aging and death will win. Now Chris is facing his most extreme and emotional challenge: three days in a retirement village while wearing an aging suit that turns the simplest activity into a Herculean task. He'll be carrying an extra 30 pounds around and shoes that will make him unbalanced, apart from glasses to see improperly and acoustic earmuffs. Later on, Chris is going to do a death-bed meditation. He’s testing the theory that the best way to combat aging and fear of mortality might not be to fight it but accept it,

Mars is infested with robots, orbiting the planet and roaming the Martian surface on a mission to uncover its secrets; now, Perseverance joins this dedicated group of machines to uncover if there is, or was ever, life on the Red Planet.
Our neighbor, Mars, fascinates us. It's a planet that is similar to Earth but with some big differences. Mars is rusty, dusty, frigid, and frozen. Past missions suggest that Mars was once a very different world. The Mars we see today has completely changed from the Mars of a few billion years ago. Without a time machine to explore ancient Mars, we employ a team of high-tech robot investigators, an entire fleet of robotic spacecraft exploring the planet. Working together, they dig into Mars's past to answer the ultimate question -- did Mars once have life?
