They will tolerate young to a certain extent, but due to their aggressive male nature, they are generally annoyed by the energetic exuberance of the young, and may hurt or even kill the young.

BPPV is not a serious medical condition, but may present serious risks of injury through falling or other spatial disorientation-induced accidents. When untreated, it might resolve in days to months; however, it may recur in some people. One can needlessly suffer from BPPV for years despite there being a simple an very effective cure. Short-term self-resolution of BPPV is unlikely because the effective cure maneuvers induce strong vertigo which the patient will naturally resist and not accidentally perform. The first medical description of the condition occurred in 1921 by Róbert Bárány. Approximately 2.4% of people are affected at some point in time. Among those who live until their 80s, 10% have been affected. BPPV affects females twice as often as males. Onset is typically in people between the ages of 50 and 70.
