It's amazing how the technology nowadays has made significant  strides, we can do things that in the past no one even imagine. 

An example of the strides of technology, is the story of Wladimir Silva, a guy of 22 years who was born with Poland syndrome, a congenital and unusual illness that affect the muscular development, and that affect him with the muscular absence in the right upper region of his body and in the congenital amputation of some fingers. 

Now, thanks to strides technology, he has an artificial hand make with a 3D printer that was donated to the Teletón, an institution that helps in the rehabilitation of child with physical and mental disability.

This artificial hand was made by Jorge Zúñiga, a physiologist, with just a few and cheap materials. 

This technology advance is interesting because it will help a lot of persons that have a physical disability, and this is just a little advance but with a big impact to the society. In the not too distant future it will be possible to make other parts of the body maybe. 

In my opinion the technology advance is so important nowadays, because help us to do a lot of things that we can't or do it more easy. 

I hope that soon this technology can be accessible to anyone.
