Things I *don't* do as a hobby

[compilerbitch]

Inspired by Scott Adams' wonderful oneliner from his current Dilbert blog:

Atheism is religion the same way that NOT collecting stamps is a hobby

I just started wondering if you lot had antihobbies. An antihobby isn't the absence of a hobby -- I mean, there are loads of things I don't do, like polevaulting for example, but I can't say that I make a hobby of not polevaulting.

<flamebait>Vegetarianism, for some people, appears indistinguishable to others as making a hobby of not eating meat.</flamebait>

Discuss.

It's interesting, isn't it?

I love playing with ideas that break classical logic, and this is a good one! If you disallow ¬¬x = x, all sorts of fun stuff happens.

I'm fond of logics that have a Hasse diagram like


*
/ \
F T
\ /
B


where F = false, T = true, * = top (could be either F or T) and B = bottom (no information)

This lets you quite elegantly deal with nondeterminism, so you can say things like F /\ * = F, T \/ x = T, etc.

Things get even more fun if you allow values to change over time, however!

(though of course these typically *do* allow ¬¬x = x, it's just yet more weirdness)
