Genuinely curious, what are some of the reasons you keep them around?

Every time I read about someone with that kind of tab count I immediately wonder:

1) if they have that many persistent tabs and actually need (probably the wrong word here) them, how many tabs do they actually close?

2) Does closing a long standing tab invoke a physiological/emotional response?

I'm only poking a little fun with #2. I have to actively overrule my subconscious when it comes to a few categories of physical things. Small electronics and computer parts/peripherals are a couple of things that if I don't verbally tell myself "you won't ever need this random old PC case panel thumb screw" I could very easily end up in hoarder territory.
