My father showed me how much faster hot water freezes in an experiment we did when I was a kid. How many of us owe our fathers for what seems to be innate curiosity now that we are adults :)

I've done it a bunch of times and never had hot water freeze faster. How did you (or your dad) set it up?

And/or you inherited the curiosity trait.

I fall on the side of nurture with regard to curiosity. _Everybody_ has "the curiosity trait", but in some environments it's discouraged: "Stop asking so many questions.", or "I don't know and why do you care?", or simply giving wrong answers.

Or the "prove your mom wrong" trait. That seemed to be his motivation, heh-heh.
