  Wow, this is a tough question!
  
  Well, I personally find it very sad that some people in other countries can’t afford to see a doctor. I’ve seen very poor people in my mum’s country (Philippines) who can’t. Lots of countries don’t have a free healthcare system like we do! I want these people to be able to have a cheap microchip sent to their house, which they can use when poorly to find out what illness they have.
  
  There are other people working on making things for disabled people though: a lot of engineers are currently making 3D-printed prosthetics for people born without limbs (, ). These prosthetics can be made to exactly fit each person, and look exactly how they want!
