Speaking with AFP from confinement with his family in Canada, retired astronaut Chris Hadfield shares some tips from his 20-year training and five-month stretch of self-isolation as commander on board the International Space Station, some of which he has published in a book, "An Astronaut's Guide to Life on Earth." Active on social media, Hadfield has already published a short YouTube video with advice including "have a mission" and stay calm by "becoming an expert" on whatever makes you fearful.
