The recent increase of old people will potentially bring about a grave socio-economical effect. Thus, the system of reemploying them should be effectively pursued. Their reemployment, along with the rearrangement of work places and the development of jobs meeting their physical, mental and psychological characteristics, will help keep up their productivity and safety as well. The change of physical functions arising from age increase can be blown from a comparison with those of young people. This study concerning the aged people's speed of judgment and limbs movement in comparison with young counterparts, I hope, will aid in designing the old population's proper jobs and work places.
