Hair-Boating
From KayakWiki
hair-boating - a potentially dangerous syndrome characterized by an irresistable urge to paddle in conditions that challenge the limits of sanity.
Examples include intense class V white water and coastal storm kayaking. This style of kayaking is most pronounced in patients suffering from severe testosterone poisoning. The testosterone correlation is strong, but not absolute since estrogen-laden homo-sapiens have also been found to suffer from this syndrome.
