I think I've taken a deliberate action on anything I've considered enough to notice it exists. Of course, if this is not the case, I can't tell, because I can't think of anything I've not thought about (if you see what i mean). For instance, I have always thought I would find smoking too addictive, although I did try it once (Adrian smokes occasionally) and it made me cough for about 5 minutes and completely decreased my tolerence of others smoking for a few days. So I think that was my first and last drag. Other things (recreational drugs, alcohol, dangerous sports etc.) get considered and slotted into a: I will try that as soon as the oppertunity presents itself, b: I might try it, but I'm in no rush to, and c: there is nothing on the planet that would get me to try that (hard drugs and bungee jumping fit this category ;-) )
