I can’t imagine a race of humans who don’t sleep. sleep is needed to regenerate the brain , sleep is awesome!
Imagen a race of humans which can work without becoming tired and remember each conversation they’ve ever said… Sounds science fiction doesn’t it. Well not anymore as scientists are already working out it out. They will insert a little device in your brain that will record your memories and conversations, this then will help people who lost there memory to remember there memory.
Overall I think it will help us a lot with remembering important information and also help us to create eventually a “super” human.
