Everyone seems to have concluded that the ants liked the Coca-Cola because it has more sugar. Actually, it has less sugar. But it tastes sweeter than Pepsi when flat, because it has more salt. The ants preferred Pepsi at the start because it was less carbonated, making it sweeter.
It completely depends on the person and the fight. I’m pretty much good to go in a couple minutes unless there was some serious betrayal that led to the fight. My wife needs anywhere between 1 and 3 days. Thankfully we really only fight about once a year, and it’s always over some completely pointless bullshit.
