1. NASA drew inspiration from baby Giraffes
Weightlessness has always been a problem in outer space, humans are not very well adapted to the lack of gravity and this plays havoc with Astronauts circulatory system. When astronauts have a lengthy stay in space, their leg veins get weaker, due to the fact that the circulatory system of the legs don’t have to work as hard to pump the blood back up the body. This means astronauts veins get lazy and weak, causing quite a few problems when they return back to Earth!
NASA circumvented this problem by studying baby giraffes, baby giraffes learn how to stand immediately after being born, due to their rapidly inflating leg veins! NASA took this incredible natural adaptation and applied it to create the Lower Body Negative Pressure Process. This device seals around the astronauts waist and applies vacuum pressure, rapidly expanding the leg veins and making blood rush into the legs and pelvic area. When this pressure is applied regularly, the astronaut’s leg veins remain as strong as they would on Earth!
2. No need for sun cream!
Due to the fact Giraffes tongues are out so frequently, grazing on vegetation, they have evolved a blueish/black colour, ensuring they don’t burn under the African sun!
3. Or hands
Giraffes tongues are up to 20 inches long, it is also prehensile meaning it can grasp things like vegetation!
