Did several outdoors activities in any season and weather, had been reasonably good at several sports, currently voluntarily teaching sailing for several sailing clubs, so I might not be at comp for weeks or monthss at a time.
Interested in almost everything, know something about much, and got everything I know anything about linked together. And probably most significant, am aware of how much I don't know. Even when I know something (even a lot) about something, it is surely not everything, and even (hopefully only part of) that might be wrong.
