My favourite piece of technology

Well if i have to choose one piece of technology, that will be definitely the bicycle, i think is the best thing that the man ever create. Is easy for use, you must do exercise, multiply the energy, is clean, and if you are old is the best way for exercise the legs (when some old gay run, he may had problems with his knee) I really dont use too much, because i live in a big city, and there are too many cars, and you truly dont enjoy a lot the trip. Without doubt is for me, far far a way the best invent ever... But i have to say the invent that change my live, is the contact lenses, is very confortable, you dont look like a dork and you can do almost every sport without worry about your glasses. And finally i cannot let scape my favourite musical instrument, this must be the Quena, that make a magical sound, and is really peacefull when you hear a melody from this. And the most important, is that instrument is very small and you load on when you are traveling without a problem.

well... now i say good bye
