He was born with a rare disease, "it's called Poland syndrome." It lacks the pectoral muscle and its right arm. With only five years, his parents gave him his first Lego, "Lego Titanic" and what began as a game has become something miraculous. "When I was little, I was very nervous being with other children, because I was different." Its difference has been its spur. This young Spaniard, David Aguilar, built his own arm. "With 18 years, last year I built this prosthesis, I called it MK1", because of its resemblance -he says- with Iron Man. David, thanks to the small plastic pieces of Lego, has one arm. Your life is perfectly normal. But he laments for all those other children who, he says, suffer harassment for not being equal to others, so, the first thing he wants to do is finish his career and build "give them a prosthesis, even free, so they feel like a Normal person". Their motto is that nothing is impossible and that disability can not stop them.
