Somewhere 2-3 years back, we did a PB survey here on the forum to see who, as kids, had aquariums while growing up.

I thought it would be close to a slam dunk that most of us grew up with aquariums, but it was not that skewed.

I'll have to dig up the link. It made for an interesting read on the cross-section of all of us.

EDIT: Here's the link:

Excerpt from Robert Crais' "The Monkey's Raincoat:"
"She took another microscopic bite of her sandwich, then pushed it away. Maybe she absorbed nutrients from her surroundings."
