To have a head for heights means that one has no acrophobia (irrational fear of heights), and is also not particularly prone to fear of falling or suffering from vertigo (the spinning sensation that can be triggered, for example, by looking down from a high place).
A head for heights is frequently cited as a requirement when mountain hiking or climbing for a particular route, as well as when paragliding and hang-gliding. It is needed for certain jobs, such as for wind turbine technicians, chimney sweeps, roofers, steeplejacks and window cleaners.Mohawk ironworkers have worked for generations erecting New York City skyscrapers,but the idea that all Mohawk people have an innate skill for doing so is a myth.
