While the functional elements of MEMS are miniaturized structures, sensors, actuators, and microelectronics, the most notable (and perhaps most interesting) elements are the microsensors and microactuators.
The horse (Equus caballus) has made many dramatic and significant journeys. During the Pleistocene (Ice Age), more than 20,000 years ago, wild horses that had evolved in America migrated to the Old World, Eurasia and Africa. More than 6,000 year ago in the Volga basin of eastern Europe horses were domesticated and in the subsequent millennia spread to other parts of Asia, Europe, and Africa.
The oldest horse was Old Billy, who lived to be 62. If well taking care of I have seen horses live for as long as 30 years. Most horses can live up to 35 years old but certain breeds can live up to 40 years old e.g lippizzanas. by mirren. It depends on how you take care of it.
