Crystal Chigbu, a Nigerian lady narrated to BBC News how she quit her job to focus on creating artificial legs for kids who don't have legs. Crystal Chigbu decided to carry out the activity of creating artificial legs because her daughter also had no legs

She gave birth to her daughter without bones on her legs, her daughter was born boneless. The doctor advised her to get rid of the boneless legs and replace 'em with an artificial leg so that her daughter can be able to walk around like her peers. 

Chigbu agreed, then an artificial leg was inserted on her daughter. After that, she thought that there will be many other children out there who will also be in the same situation with her daughter. She decided to also help them by providing artificial legs for them for free. She quit her job, gathered a team that helped her to actualize her dream. 

They started creating artificial legs and also started distribution the legs to kids who have no legs or those who lost their legs. This was done by her to these kids for free so that they will be opportuned to walk around like their peers.
