Why do most people choose mechanical engineering as a career?

yes it is difficult to explain but i think it is a discipline of engineering, and it is oldest one. think how our body works ?? because of mechanism. and this mechanism controls our body due to this we take any type of decision and we do anything.and my next example is - why we wear a different types of cloths?? because we like its fitting, stitching and many more but think again who gives fitting to cloths, who give stylish look to cloth ......only machines only tools. so i think everything is depends on machines from needle to aeroplane. so for me mechanicle engineering is so intresting and it is so enjoyable.
