We’d like to thank Focus Features for sponsoring this video – and for inviting us to pre-screen their summer 2015 film “Self/Less”. It’s a sci-fi flick that explores memory, consciousness, and immortality, and it made us think about the types of immortality that already exist here on Earth. A big thanks to Focus Features for supporting MinuteEarth! http://www.focusfeatures.com/selfless Thanks also to our Patreon patrons: - Today I Found Out - Jeff Straathof - Maarten Bremer - Mark - BurmansHealthShop - Alberto Bortoni - Avi Yashchin - Valentin - Nicholas Buckendorf - Antoine Coeur YOU can also support us on Patreon: https://www.patreon.com/minuteearth ___________________________________________ Want to learn more about the topic in this week’s video? Here are some key words/phrases to get your googling started: – negligible senescence: not showing signs of age-related progression – biological immortality: having a mortality rate that does not increase with increasing age ________________________ MinuteEarth provides an energetic and entertaining view of trends in earth’s environment – in just a few minutes!
