WOW! Just WOW! I've always thought you had to be in perfect shape and condition in order to be an astronaut, but John proved me wrong! He was one of the 17 candidates to be picked to be astronauts out of 22,500 candidates! He must've been so proud to find out he had qualified, even with his disability! It's upsetting how he lost his leg though, I'm glad he has a prosthetic one! Today's technology really does change lives, and in the case of John, for the better! Speaking of prosthetics, did you know that a single prosthesis can cost you up to $100,000? That is pretty expensive! However, the 3-D printing technology can change that and reduce the cost to as low as $4,000!! What a change! Did you also know that 77% of all the amputation processes are performed on males? I found that pretty interesting! Anyways, I hope John will be about to go to space, he deserves it after being through so much! ❤️❤️🌕🦿 #staystrong #keepgoing #tothemoonandback #astronaut #skyisthelimit #shootforthestars
