Moreover, so as to cope with strong winds and earthquakes, the structure must be basically flexible, so at high levels the architecture will actually move slightly. "Stand above 20 storeys and look down, you will see the building really does move and that it is no illusion," says Hu Pao-lin. This normal architectural movement can have adverse effects on the elderly.
而高樓為應付可能來襲的強風、地震，結構體本身需具備相當的彈性，因此在相當高度時，建築物會以極微小的角度搖晃，「站在廿樓以上高度向下望，建築物真的會晃，並非錯覺」，胡寶林表示，建築物經常性的晃動，對老人可能不是件好事。
