I think I tend to form an opinion on whether I should or shouldn't try any new activity I find out about... I don't have a 'neutral' category of things which I don't consider trying.

I used to have a motto to live by, "I'll try anything twice", but then I started running a fetish site and decided that actually that was a little too all-encompassing... there are some activities that I have no wish to try before deciding I'm disinterested in them! :) But I do tend to feel an (often quite strong) inclination to try anything which doesn't initially repulse me, just to see if I like it or not, and how much.

ObGum:
I only started chewing gum a few years ago, when I was taking a lot of stimulants - it's a common way to prevent damaging your teeth by grinding them while under the influence. I stopped chewing gum when I stopped taking stimulants last year, and don't miss it - I only ever did it for a very specific reason. I suppose I can see a point to using gum as a backup breath freshener, other than that it seems fairly tedious to me...
