Lone sailors, mountain climbers etc, are usually adepts at their sport, go well prepared, well equipped and, while the dramatic rescues catch the news, in comparison with the many sailors, for example, who sail the oceans, alone or with a few others, the proportion that get into trouble, usually as the result of exceptional events, is very few indeed.
Deliberately seeking danger, is something very different.
