Baada ya muda, baadhi ya Them inaweza kutega vile hivyo kubwa Hiyo unazidi angle kikomo, ambayo ni kuendelea kudhoofisha tishu chini ya mabua bado uweza Kudumisha. athari za uzito wa bua na kila shahada kitanzi cha kupotoka huongezeka athari ya lever, na wakati fulani, bua inaweza Relativt Haraka bend chini.
